[(8-3)×5]-1=24

[(5)×5]-1=24

[5×5]-1=24

[25]-1=24

25-1=24

24=24

Using the numbers 8, 3, 5, and 1 with multiplication, negative numbers, and division, you can form the equation (8 - 5) × 3 = 24.

Sure, let's find an equation that equals 24 using the numbers 8, 3, 5, and 1 with the operations of multiplication, negative numbers, and division:

Equation: (8 - 5) × 3 = 24

See calculation below:

Start with the number 8 then subtract 5 to get 3.

Multiply 3 by 3 to get 9 and then multiply 9 by -1 to get -9.

Subtract -9 from 24 to get 33.

So, the equation (8 - 5) × 3 = 24 is achieved using the numbers and operations you specified.

This remains the same on the moon as on Earth.  --> MASS

This results from the pull of gravity.  --> WEIGHT

This relates to the amount of matter in an object.  --> MASS

This will change in space.  --> WEIGHT

mass is a SCALAR, weight is a VECTOR

Step-by-step explanation:

In physics:

- The mass of an object is a scalar quantity that gives a measure of the "amount of matter" in an object. It is an intrinsec property of the object, therefore its value does not depend on the location of the object.

- The weight of an object is the force of gravitational attraction exerted on the object. Being a force, it has a magnitude and a direction. Its magnitude is given by

[tex]F=mg[/tex]

where m is the mass of the object and g is the acceleration due to gravity at the location of the object. Therefore, its value depends on the location.

Now we can identify correctly each statement given:

This remains the same on the moon as on Earth.  --> MASS

x < 3

There are 20 dimes and 80 quarters

Solution:

Let "d" be the number of dimes

Let "q" be the number of quarters

1 dime = $ 0.10

1 quarter = $ 0.25

Panchito Pantera has 100 coins

Therefore,

number of dimes + number of quarters = 100

d + q = 100 ----------- eqn 1

He has a total of $22. Thus we frame a equation as:

number of dimes x 0.10 + number of quarters x 0.25 = 22

[tex]d \times 0.10 + q \times 0.25 = 22[/tex]

0.1d + 0.25q = 22 --------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

d = 100 - q ------- eqn 3

Substitute eqn 3 in eqn 2

0.1(100 - q) + 0.25q = 22

10 - 0.1q + 0.25q = 22

0.15q = 22 - 10

0.15q = 12

Divide both sides by 0.15

q = 80

Substitute q = 80 in eqn 3

d = 100 - 80

d = 20

Thus there are 20 dimes and 80 quarters

Answer: 155

Step-by-step explanation: Well percent means over 100 so we can set up an equation for this problem by reading it from left to right.

What number means x, is means equals,

62% is 62/100, of means times 250.

So we have the equation  x = 62/100 · 250.

Simplifying on the right side side of the equation, notice that 62/100 reduces to 31/50 so we have x = 31/50 · 250.

Think of the 250 as 250/1.

So we can cross cancel the 250 and 50 to 50 and 1.

So we 31 times 5 over 1 or 155.

So 155 is 62% of 250.

Answer:  A-122-102=c2

Step-by-step explanation: This is the answer to the missing side length in the right triangle shown.

Option B: 122 + b^2 = 102^2 is the correct equation to find the missing side length in the right triangle.

The equation that would help you find the missing side length in the right triangle is option B: 122 + b2 = 1022.

In a right triangle, the Pythagorean theorem states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, 122 is the length of one side and 102 is the length of the other side. By rearranging the equation, you can solve for the missing side length, b.

Let's rewrite the equation using the proper square notation:

122 + b2 = 1022

122 + b2 = 10404

b2 = 10404 - 122

b2 = 10282

b = √10282

b ≈ 101.4

Question:

The equations in this system were added to solve for x. What is the value of x? -2x+y=8 5x-y=-5 3x=3

Options:

x = negative 3

x = negative 1

x = 1

x = 3

Answer:

The value of x is 1

Solution:

Given system of equations are:

-2x + y = 8 ------- eqn 1

5x - y = -5 ------- eqn 2

The above equations are added to solve for "x"

Add eqn 1 and eqn 2

-2x + y + 5x - y = 8 - 5

Combine the like terms

-2x + 5x + y - y = 3

Add the like terms

3x + 0 = 3

3x = 3

Divide both sides of equation by 3

x = 1

Answer:4,6,8,10,12,14,16,18,20

Step-by-step explanation:

Basically all even numbers.

Answer:

1 -1/5 is the answer #markasbrainliest

The equivalent options are:

"One-sixth x + 47" ⇒ 2nd

"1 and two-thirds x + 35 minus 1 and one-half x + 12" ⇒ 3rd

"5 (one-third x) + (5) (7) minus (3) (one-half x) + (3) (4)" ⇒ 4th

Step-by-step explanation:

The expression is: 5( [tex]\frac{1}{3}[/tex] x + 7) - 3( [tex]\frac{1}{2}[/tex] x - 4) to find the equivalent to it:

Multiply the bracket ( [tex]\frac{1}{3}[/tex] x + 7) by 5

∵ 5( [tex]\frac{1}{3}[/tex] x + 7) = 5(

Multiply the bracket ( [tex]\frac{1}{2}[/tex] x - 4) by - 3

∵ -3( [tex]\frac{1}{2}[/tex] x - 4) = -3(

∴ 5( [tex]\frac{1}{3}[/tex] x + 7) - 3( [tex]\frac{1}{2}[/tex] x - 4) =  [tex]\frac{5}{3}[/tex] x + 35 -  [tex]\frac{3}{2}[/tex] x + 12

Add the like terms

∴ 5( [tex]\frac{1}{3}[/tex] x + 7) - 3( [tex]\frac{1}{2}[/tex] x - 4) = ( [tex]\frac{5}{3}[/tex] x - [tex]\frac{3}{2}[/tex] x) + (35 + 12)

To add fraction with different denominators find the LCM of the two denominators and change them by it, then divide the LCM by each denominator and multiply the quotient by the corresponding numerator

∵ LCM of 3 and 2 is 6

∵ 6 ÷ 3 = 2, then multiply 5 by 2

∴  [tex]\frac{5}{3}[/tex] = [tex]\frac{10}{6}[/tex]

∵ 6 ÷ 2 = 3, then multiply 3 by 3

∴ [tex]\frac{3}{2}[/tex] = [tex]\frac{9}{6}[/tex]

∴ ( [tex]\frac{5}{3}[/tex] x - [tex]\frac{3}{2}[/tex] x) =  [tex]\frac{10}{6}[/tex] x -  [tex]\frac{9}{6}[/tex] x = [tex]\frac{1}{6}[/tex] x

∵ 35 + 12 = 47

∴ 5( [tex]\frac{1}{3}[/tex] x + 7) - 3( [tex]\frac{1}{2}[/tex] x - 4) =  [tex]\frac{1}{6}[/tex] x + 47

The 1st option is "One-sixth x + 47"

In the step 5( [tex]\frac{1}{3}[/tex] x + 7) - 3( [tex]\frac{1}{2}[/tex] x - 4) =  [tex]\frac{5}{3}[/tex] x + 35 - [tex]\frac{3}{2}[/tex] x + 12

∵  [tex]\frac{5}{3}[/tex]  = [tex]1\frac{2}{3}[/tex]  and  [tex]\frac{3}{2}[/tex] = [tex]1\frac{1}{2}[/tex]

∴  [tex]\frac{5}{3}[/tex] x + 35 - [tex]\frac{3}{2}[/tex] x + 12 = [tex]1\frac{2}{3}[/tex] x + 35 - [tex]1\frac{1}{2}[/tex] x + 12

∴ 5( [tex]\frac{1}{3}[/tex] x + 7) - 3( [tex]\frac{1}{2}[/tex] x - 4) =  [tex]1\frac{2}{3}[/tex] x + 35 - [tex]1\frac{1}{2}[/tex] x + 12

The 2nd option is "1 and two-thirds x + 35 minus 1 and one-half x + 12"

∵ 5( [tex]\frac{1}{3}[/tex] x + 7) = 5(

∵ -3( [tex]\frac{1}{2}[/tex] x - 4) = -3(

∴ 5( [tex]\frac{1}{3}[/tex] x + 7) - 3( [tex]\frac{1}{2}[/tex] x - 4) = 5(

The 3rd option is "5 (one-third x) + (5) (7) minus (3) (one-half x) + (3) (4)"

Answer:(please note im not sure)

3/8 (i think).

Step-by-step explanation:

The probability of this not happening in an event is 3/8.

Probability is a measure of the likelihood or chance that a particular event or outcome will occur. It quantifies the uncertainty associated with different possible outcomes in a given situation. In other words, probability helps us understand the likelihood of an event happening.

The probability of not happening of an event is calculated by subtracting the probability of happening of an event.

The probability of not happening of an event is,

P(not) = 1 - P

P(not) = 1 - 5/8

P(not) = 3 /8

Therefore, the probability that the event will not happen is 3/8.

Answer: [tex]\frac{1}{4}\ cups[/tex]

Step-by-step explanation:

For this exercise it is important to analize the information given in the exercise.

 According to the data provided in the exercise, the recipe says that [tex]\frac{1}{2}\ cups[/tex]  of Parmesan serves four people.

 The, let be "x" the amount of cups of Parmesan cheese that Cordelia will use for her brother's proposal dinner.

In this case, since the proposal dinner is for two people, you can set up the following proportion:

[tex]\frac{4}{\frac{1}{2}}=\frac{2}{x}[/tex]

Finally, you must solve for "x" in order to find its value, as you can observe below:

[tex]8=\frac{2}{x}\\\\8x=2\\\\x=\frac{2}{8}\\\\x=\frac{1}{4}[/tex]

Therefore, knowing the value of "x", you can determine that Cordelia will use [tex]\frac{1}{4}\ cups[/tex]  of Parmesan cheese for the proposal dinner.

where d is the number of decades after the population was measured. Evaluate the expression for d = −2

Given :

The number of  finches is modeled by the expression  :

⇒ [tex]45\cdot1.5^d[/tex]

where [tex]d[/tex] is the number of decades after the population was measured.

To evaluate the expression for d=-2

Solution:

In order to evaluate the given expression to find the number of finches at [tex]d=-2[/tex], we will plugin [tex]-2[/tex] for [tex]d[/tex] in the expression and simplify it.

Plugging in [tex]d=-2[/tex] in the expression:
