5.5x + 3 = y
7x =y

5.5x + 3 = 7x (-5.5x both sides)

3 = 1.5x (÷1.5 both sides)

X = 2

Michael takes two hours

Solve<br> 6x−10(x+12)=−4x−24<br> Show your work.

gladu [14]

6x - 10(x + 12) = -4x - 24

<em><u>Distributive property.</u></em>

6x - 10x - 120 = -4x - 24

<em><u>Add 10x to both sides.</u></em>

6x - 120 = 6x - 24

<em><u>Cancel like terms.</u></em>

<em>Add 24 to both sides.</em>

-96 ≠ 0.

This equation is incorrect, as -96 will never be equal to 0.

What integer $x$ satisfies $\frac{1}{4}<\frac{x}{7}<\frac{1}{3}$?

Zarrin [17]

If 1/4 < x/7 < 1/3, then

7/4 < x < 7/3

1.75 < x < 2.333…

so that x = 2.

Brian received a gift card of $60 for a pizza restaurant. The restaurant charges $5 per pizza. Ashley received a gift card of $1

Semmy [17]

Ashley can purchase 10 pizzas and Brian can purchase 12 so there would be nothing left on the cards

5/60=12

10/100=10
