Question

Help me answer these my parents called me a disappointment. ​

Answer 1

1, 4, 20, 1

Explanation:

p is 1/3, while m is 2.

These are variables assigned to a number. When solving, we have to substitute these numbers in for the assigned variables.

5. 3p

Since p is 1/3, let's plug in 1/3 into the equation.

3(1/3)

3 times 1/3 of a cookie is just one. So the answer is 1

6. 12p

p is known as 1/3 again, so let's plug it in to the equation.

12(1/3), or better written as
`(12)/(1) *(1)/(3)`

To multiply fractions, we just go multiply the numerators and denominators and make it divided by each other.

We get
`(12)/(3) =4`, so the answer is 4

7. 12m-4

We know that m is 2, so let's plug that in.

12(2)-4

Knowing PEMDAS, the order of which we solve equations (parenthesis, exponent, multiplication, division, addition, and subtraction), let's solve 12 times 2 first.

24-4=20, the answer is 20

8.9p^2

We know once again p is equal to 1/3, so let's plug it in.

`9((1)/(3)) ^2`

The power of 1/3 to the second power is just 1/3 times 1/3, which is 1/9.

9(1/9)= if we have 9 pieces of cookies divided in 1/9ths, we will have one cookie. So the answer is 1
