solve the system of equations 2x+2y=6z=8 5x+6y+5z=3 5x+6y+3z=5

Answer:

y or f(x), depends on the context.

Step-by-step explanation:

When graphing a function, we input a value, x, and output a value, y. This is why we have a coordinate plane.

For example, if we have y = 2x and x=2, our input, then y = 4, our output.

However, if written in function notation, f(x) = 2x, our output will still be 4, except that our output is f(x)

Answer:

f(x)

Step-by-step explanation:

To find the area of the orange band, subtract the area of the yellow square from the area of the larger square.

To find the area of the orange band, we need to subtract the area of the yellow square from the area of the larger square. The side length of the larger square is 8 inches because it is twice the side length of the yellow square, which is x inches. So, the area of the larger square is 8 * 8 = 64 square inches. The area of the yellow square is x * x = x^2 square inches. Therefore, the area of the orange band is 64 - x^2 square inches.

Final answer:

To calculate the area of the orange band, find the area of the larger square using the side length of x + 22 inches and subtract the area of the smaller yellow square with side length x. The expression for the area of the orange band is [tex](x + 22)^2 - x^2[/tex], which simplifies to 44x + 484 square inches.

Explanation:

To calculate the area of the orange band, you need to determine the area of the outer (larger) square and subtract the area of the inner (smaller) yellow square. First, find the side length of the larger square, which is the side length of the yellow square plus twice the width of the orange band, so it's x + 2(11) inches. Thus, the side length of the larger square is x + 22 inches.

Now, calculate the area of both squares. The area of the larger square is [tex](x + 22)^2[/tex] square inches, and the area of the yellow square is [tex]x^2[/tex] square inches. The area of the orange band is the difference between these two areas:

Area of the larger square:[tex](x + 22)^2[/tex]

Area of the yellow square: [tex]x^2[/tex]

Area of the orange band: [tex](x + 22)^2 - x^2[/tex]

To find the area of the orange band, you expand the expression [tex](x + 22)^2[/tex], which gives you [tex]x^2 + 44x + 484[/tex], then subtract the area of the yellow square [tex]x^2[/tex], resulting in 44x + 484 square inches, which is the area of the orange band.

It would take 6.99 kilometers of thread to make 9 boxes of shirts.

Step-by-step explanation:

Step 1; First we convert the mixed fractions into improper fractions. So

2[tex]\frac{1}{5}[/tex] becomes [tex]\frac{11}{5}[/tex] after multiplying 2 with 5 and adding 1 while 5 remains.

2[tex]\frac{5}{6}[/tex] becomes [tex]\frac{17}{6}[/tex] after multiplying the 2 with 6 and adding 5 while 6 remains.

Step 2; Next we equate the given data; [tex]\frac{11}{5}[/tex] kilometers of thread = [tex]\frac{17}{6}[/tex] boxes of thread. We must make the RHS equal to 1 to find out the kilometers of thread needed to make 1 box of shirts. So we multiply [tex]\frac{6}{17}[/tex] on both sides to make the RHS equal to 1.

[tex]\frac{11}{5}[/tex] × [tex]\frac{6}{17}[/tex] = [tex]\frac{17}{6}[/tex]× [tex]\frac{6}{17}[/tex]= 1, So [tex]\frac{11}{5}[/tex] × [tex]\frac{6}{17}[/tex] = [tex]\frac{66}{85}[/tex] km of thread. So [tex]\frac{66}{85}[/tex] kilometers of the thread is required to make 1 box of shirts so we multiply this with 9 to see thread required to make 9 boxes of shirts.

Thread required for 9 boxes of shirts = [tex]\frac{66}{85}[/tex] × 9= [tex]\frac{594}{85}[/tex] = 6.9882 kilometers of thread. This is rounded off to 6.99 kilometers of thread.

2+1=3

3+3=6

Two equations that have the solution (3,6) include y = 2x and x + y = 9, satisfying the point when their values are substituted.

To write two equations that would have the solution of (3,6), we need to construct linear equations where the point (3,6) satisfies both equations. Here are two examples that fit the criteria:

The first equation could be y = 2x, because when x=3, then y=2(3)=6.

The second equation could be x + y = 9, because when x=3 and y=6, then 3 + 6 = 9.

These two examples clearly have the solution (3,6) when the respective values for x and y are substituted.

Answer: he is right the answer is -2

Step-by-step explanation:

The common difference (d) is -2.

In an arithmetic sequence, the common difference (d) is the constant value by which each term differs from the previous term.

To find the common difference in the sequence 100, 98, 96, 94, 92..., we can observe the difference between consecutive terms:

98 - 100 = -2

96 - 98 = -2

94 - 96 = -2

92 - 94 = -2

We see that each term is decreasing by 2. Therefore, the common difference (d) is -2.

Final answer:

Mikey the monkey ate more bananas than Mick, consuming 5 compared to Mick's 4 bananas.

Explanation:

Let's calculate how many bananas each monkey ate. We'll start with Mick the monkey, who had 10 bananas and ate two fifths of them.

Calculate two fifths of 10 bananas: (2/5) × 10 = 4 bananas.

Mick therefore ate 4 bananas.

Now, let's calculate for Mikey the monkey, who also had 10 bananas and ate half of them.

Calculate half of 10 bananas: (1/2) × 10 = 5 bananas.

Mikey ate 5 bananas.

Mikey the monkey ate more bananas than Mick because 5 is greater than 4.

Answer:

The price of a drink = $4

The price of a bag of popcorn = $5.5

Step-by-step explanation:

Let p represent popcorn and d represent drink

Harper bought 10 bags of popcorn and 6 drinks and paid $79 ➡ 10p + 6d = $79

Damian bought 3 bags of popcorn and 5 drinks and paid $36.50 ➡ 3p + 5d = $36.50

Now multiply first equation by -3 and second equation by 10

-3 × (10p + 6d) = $79 ➡ -30p - 18d = -$237

10 × (3p + 5d) = $36.50 ➡ 30p + 50d = $365

Now add the new equationd

30p + 50d -30p - 18d = $365 - $237 (-30p will eliminate 30p)

32d = $128 divide both sides of the equation by 32

32 ÷ 32d = 32 ÷ $128 ➡ d = 4

If d = 4 that means a drink costs $4 we can use this information to find the price of a bag of popcorn

3p + 5d = $36.50 (replace d with 4)

3p + 4×5 = $36.50

3p + 20 = $36.50

3p = $36.50 - 20

3p = 16.50 divide both sides by 3

p = $5.5

The question asked to set up a system of equations to determine the price of each bag of popcorn and each drink. Using the variables x and y to represent the price of popcorn and drinks respectively, the system of equations based on the information given is 10x + 6y = $79 and 3x + 5y = $36.50.

To solve this problem, we need to setup a series of equations based on the information given. Let's say:

According to the first scenario with Harper, we get:

10x + 6y = $79

From Damian's shopping, we have:

3x + 5y = $36.50

This gives us the system of equations which can be used to find individual prices of a bag of popcorn and a drink.

Step-by-step explanation:

7+4=11

7-4=3

To find the value of two numbers if their sum is 11 and the difference is 3, we can use a system of equations. The two numbers are 7 and 4.

To find the value of two numbers if their sum is 11 and the difference is 3, we can use a system of equations.

Let's call the two numbers x and y. We can set up the following equations:

x + y = 11

x - y = 3

Now we can solve this system of equations by adding the two equations together:

(x + y) + (x - y) = 11 + 3

Simplifying, we get:2x = 14

Dividing both sides by 2, we get:x = 7

Now we can substitute this value of x back into one of the original equations to solve for y:7 + y = 11

Subtracting 7 from both sides, we get:y = 4

So, the two numbers are 7 and 4.

Answer:

B-false

Step-by-step explanation:

It is false because where the 2 is, has to be 3, other wise it won't make sense. Because it will not equal the same thing.

Final answer:

The expression 3a + 3b is not equivalent to 3(a + 2b). The first results in 3a + 3b, while applying the distributive property to the second expression gives 3a + 6b, clearly showing the expressions are different.

Explanation:

The statement 3a + 3b is equivalent to 3(a + 2b) is false. To show this, we can apply the distributive property of multiplication over addition, which states that for any real numbers a, b, and c, a · (b + c) = a·b + a·c. Using this property, we can expand 3(a + 2b) to get 3·a + 3·2b, which simplifies to 3a + 6b. This is not the same as 3a + 3b since 3b is not equal to 6b. Therefore, the expressions are not equivalent.

Answer:

First term: A(1) = 5

Fourth term: A(4) = 5 1/2

Tenth term: A (10) = 6 1/2

Step-by-step explanation:

Let's find the first, fourth and tenth terms of the arithmetic sequence described by the given rule:

A(n) = 5 + (n-1) (1/6)

First term:

A(1) = 5 + (1-1) (1/6)

A(1) = 5 + (0) (1/6)

A(1) = 5

Fourth term:

A(4) = 5 + (4-1) (1/6)

A(4) = 5 + (3) (1/6)

A(4) = 5 + 3/6 = 5 3/6 = 5 1/2 (simplifying)

Tenth term

A(10) = 5 + (10-1) (1/6)

A(10) = 5 + (9) (1/6)

A (10) = 5 + 9/6 = 6 3/6 = 6 1/2 (simplifying)

Answer: Perimeter = 2(L + W) and

as a simplified expression is, 8x + 2

Step-by-step explanation: The length is represented by L and the width is represented by W in the expression above.

However, since we have been given the sides of the rectangle as x + 2 and 3x - 1, we shall substitute for the values of these in the expression representing the perimeter.

2(L + W) can now be written as

2( {x + 2} + {3x - 1} )

2(x + 2 + 3x - 1)

By collecting like terms, we now have

2(4x + 1)

8x + 2.

The dimensions of the rectangle will allow for the most economical fence to be built are 30 feet by 15 feet

Given that, rectangular area=450 square feet.

The formula to find the area of a rectangle is Area=Length×Breadth.

Let the length of the rectangle be x and the breadth of the rectangle be y.

Now, 450=xy.

x=450/y

The cost of three sides is $3 per foot.

That is, 3x+3x+3y

The cost on the fourth side is $9 per foot.

That is, 9y

Total cost=6x+12y

Now, Total cost=6×450/y+18y

Let the minimum cost be 0.

2700/y+12y=0

⇒2700/y²-12=0

⇒12y²=2700

⇒y=15 feet

So, 450/15=x=30 feet.

Therefore, the dimensions of the rectangle are 30 feet by 15 feet.

Explanation:

Focus only on the diamond cards. There are 13 of them total. Out of the 13 diamond cards, there is one king of diamonds. So the probability of getting a king, if we know 100% the card is a diamond, is 1/13.

---------------

You can use a slightly longer method through a conditional probability

A = card is a king

B = card is a diamond

P(A and B) = probability of king and diamonds = 1/52

P(A \ B) = probability of event A happens given we know B happens

P(A \ B) = P(A and B)/P(B)

P(A \ B) = (1/52)/(13/52)

P(A \ B) = (1/52) ÷ (13/52)

P(A \ B) = (1/52) * (52/13)

P(A \ B) = 1/13

The probability that the card is a King is 1/13

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome

Given that a card is drawn at random from a pack of 52 playing cards, the total outcome is 52

If the card is a king, the expected outcome is 4

Pr(selecting a king) = 4/52 = 1/13

Hence the probability that the card is a King is 1/13
