– 72 = 3(- 4x – 8) Need help

Finger [1]

Answer:

x = 4

Step-by-step explanation:

Step 1: Write equation

-72 = 3(-4x - 8)

Step 2: Solve for x

Distribute 3: -72 = -12x - 24

Add 24 to both sides: -48 = -12x

Divide both sides by -12: x = 4

Step 3: Check

Plug in x to verify if it's a solution.

-72 = 3(-4(4) - 8)

-72 = 3(-16 - 8)

-72 = 3(-24)

-72 = -72

X:y=5:3 and x+y=56 what is the value off x-y

Rudiy27

$x:y=5:3\to\dfrac{x}{y}=\dfrac{5}{3}\qquad\text{cross multiply}\\\\3x=5y\qquad\text{divide both sides by 3}\\\\x=\dfrac{5}{3}y\\\\\text{substitute to the equation} \ x+y=56\\\\\dfrac{5}{3}y+y=56\\\\\dfrac{5}{3}y+\dfrac{3}{3}y=56\\\\\dfrac{5+3}{3}y=56\\\\\dfrac{8}{3}y=56\qquad\text{multiply both sides by 3}\\\\8y=3\cdot56\qquad\text{divide both sides by 8}\\\\y=3\cdot7\\\\y=21\\\\\text{substitute the value of y to the equation}\ x=\dfrac{5}{3}y\\\\x=\dfrac{5}{3}\cdot21=5\cdot7=35$

$Answer:\ \boxed{x-y=35-21=14}$

The label on the box says the bookshelf is 5151 inches tall. How tall is it in feet?

romanna [79]

We know, 1 inch = 1/12 feet
