You have a gift card for your favorite clothing store for the amount of $60. You have found a shirt you want for $15. You don't
Zolol [24]

Let

x--------> the amount you have left to spend

y--------> the cost of a shirt you want

z------> the amount of the gift card

we know that

x+y \leq   z --------> equation 1

y=\$ 15 --------> equation 2

z=\$ 60 --------> equation 3

Substitute the equation 2 and equation 3 in the equation [tex] 1 [/tex]

x+y \leq   z

x+15 \leq   60

therefore

<u>the answer is the option</u>

x+15 is less than or equal to 60

Question 7<br> #7) What value of m makes the equation true?<br> 3(8 – m) = 5m – 40
Anastaziya [24]

Answer:

8

Step-by-step explanation:

3(8-m)=5m-40

you first distribute 3 through the parenthesis

24-3m=5m-40

Move the variable to the left and change sign

24-3m-5m=-40

now move the constant to the right

-3m-5m=-40-24

collect like terms

-8m=-40-24

-8m=-64

Divide both sides by -8 and negative divide negative number becomes positive

so m = 8
