Step-by-step explanation:

You add them all up from least to greatest on a piece of paper then use your two fingers starting from the least and the greatest and go down the line if you get more than 1 number you must add them both up and divide by 2.

The solution set is (7,3).

Step-by-step explanation:

Given system of equations is;

3x−2y=15     Eqn 1

y=2x−11        Eqn 2

Substituting value of y from Eqn 2 in Eqn 1

[tex]3x-2(2x-11)=15\\3x-4x+22=15\\-x+22-15=0\\7=x\\x=7[/tex]

Putting x=7 in Eqn 2

[tex]y=2(7)-11\\y=14-11\\y=3[/tex]

The solution set is (7,3).

Answer: .2

Step-by-step explanation:

If the question was 25 divided by 5 it'll be 5 but because it's 5 divided by 25 the answer came out as a deciamal.

.2 can also mean it is 2/10 or maybe 20%

The value of 9 × 9 is 81.

Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.

a × b means that a is added to itself b times or b is added to itself a times.

The question is to find the product of 9 × 9.

By the definition of multiplication, 9 × 9 is the addition of the number up to 9 times.

That is, 9 × 9 can also be written as,

9 × 9 = 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9

Adding number 9 to itself 9 times we get 81.

So 9 × 9 = 81

Hence the product after multiplying 9 with 9 is 81.

Consider Δ JKL and Δ GDF

If the ratios of corresponding sides are equal then the triangles are similar.

[tex]\frac{JK}{GD}[/tex] = [tex]\frac{24}{20}[/tex] = [tex]\frac{6}{5}[/tex]

[tex]\frac{xJL}{GF}[/tex] = [tex]\frac{18}{15}[/tex] = [tex]\frac{6}{5}[/tex]

[tex]\frac{KL}{DF}[/tex] = [tex]\frac{12}{10}[/tex] = [tex]\frac{6}{5}[/tex]

Step-by-step explanation:

The first number is 8

Solution:

Let the first number be "x"

The second number is 6 times the first

Second number = 6x

The third number is 15 less than the second

Third number = second number - 15

Third number = 6x - 15

The sum of three numbers is 89

Therefore,

First number + second number + third number = 89

[tex]x + 6x + 6x - 15 = 89\\\\13x - 15 = 89\\\\13x = 89+15\\\\13x = 104\\\\Divide\ both\ sides\ by\ 13\\\\x = 8[/tex]

Thus the first number is 8

[tex]21+7.50p\leq 52[/tex]

For inequalities, "a is no more than b" can be written as:

[tex]a\leq b[/tex]

Here we know Candace that can spend no more than $52 before tax. She can spend a certain amount of money in both Dark Roast coffee and Morning Blend coffee. So she spends:

Therefore:

Amount of money for Morning Blend coffee:

[tex]2\times 10.50=\$21[/tex]

Amount of money for Dark Roast coffee:

[tex]p\times 7.50=\$7.50p[/tex]

So the total amount of money:

[tex]21+7.50p[/tex]

Finally, the inequality becomes:

[tex]21+7.50p\leq 52[/tex]

Besides, in order to know how many pounds she can spend let's solve for p:

[tex]7.50p\leq 52-21 \\ \\ 7.50p\leq 31 \\ \\ p\leq 4.13[/tex]

So she can spend less that 4.13 pounds.

Final answer:

The correct inequality to determine the possible values for the number of pounds of Dark Roast coffee, p, along with 2 pounds of Morning Blend coffee for $52 or less is 9p + 15.10 ≤ 52. This inequality can be used to solve for p, the number of pounds of Dark Roast coffee Candace can buy which is p ≤ 4.1.

Explanation:

Calculator Candace wants to determine the number of pounds of Dark Roast coffee, represented as p, she can buy if she purchases 2 pounds of Morning Blend coffee for a total of $52 or less. The price of the Morning Blend coffee is $7.55 per pound. To calculate this, we need to create an inequality that represents the scenario:

Now, the inequality will consider the total price of the Morning Blend coffee and add the price of the Dark Roast coffee (which is $9.00 per pound). So the inequality should look like this:

9p + 15.10 ≤ 52

This inequality can be used to solve for p, the number of pounds of Dark Roast coffee Candace can buy which is p≤4.1.

Answer: x= -1 y= 4

Step-by-step explanation:

We are going to solve this using substitution.

Here is the work...

5x+3(4)=7

That is what it woud look like because y is equal to 4.

3 times 4 is 12.

So now we have...

5x+12=7

Now we want to get All the common factors together...

To do this we will subtract 12 from 7 and we get -5.

Here is our equation now...

5x=-5

Now we divide x by 5 to get x alone, but we also divide -5 by 5.

x=-1

Now all we have to do to solve for y is put x in an equation.

In this case here is what we will do...

5(-1)+3y=7

Multiply...

-5+3y=7

Now we need to get the common factors together so lets add 5 to 7.

3y=12

3y/3=y

12/3=y

y=4

But that is already in your problem...OOF.Dont worry its still correct.

To solve the system, substitute y=4 into the first equation, leading to x=-1. Thus, the solution is x=-1 and y=4.

To solve the system of equations 5x + 3y = 7 and y = 4, we can start by substituting the value of y from the second equation into the first equation. We are given y directly, so the substitution is straightforward.

Substituting y = 4 into the first equation:

So, the solution to the system of equations is x = -1 and y = 4. We can say that x and y are variables, and in this case, y is dependent on x in other linear equations but is given directly here.

Answer:

40.43 Kilometers

Explanation:

19.16, 13, 8.27

19.16 + 13 + 8.27

= 40.43

Final answer:

The total distance Kira ran during the three days is the sum of the individual distances she ran on each day, which is 40.43 kilometers.

Explanation:

The total distance Kira ran on the three days is the sum of the distances she ran on each day. To find the total distance, you simply need to add up the three individual distances.

Add the first distance: 19.16 km

Add the second distance: 13 km

Add the third distance: 8.27 km

Calculate the sum: 19.16 km + 13 km + 8.27 km = 40.43 km

Therefore, the total distance Kira ran during the three days is 40.43 kilometers.

Answer:

z ÷ 3 + z

Step-by-step explanation:

Area of the figure is 532 m².

Solution:

In the given image the shape is splitted into 2 shapes.

First shape is the square.

In square 4 sides are equal.

Area of the square = side × side

                               = 18 m × 18 m

Area of the square = 324 m²

Second shape is the triangle in the bottom.

Base of the triangle = 18 m + 8 m = 26 m

Height of the triangle = 16 m

Area of the triangle = [tex]\frac{1}{2}\times{\text{base}}\times{\text{height}}[/tex]

                                 [tex]$=\frac{1}{2}\times16\times26[/tex]

Area of the triangle = 208 m²

Area of the given shape = area of the square + area of the triangle

                                         = 324 m² + 208 m²

Area of the given shape = 532 m²

Hence area of the figure is 532 m².
