No, not necessarily

Your bedroom ceiling is 10 feet high and is 2/3 as high as the living room ceiling. Write and solve an equation to find the heig

Lina20 [59]

The height of living room ceiling is 15 feet.

Step-by-step explanation:

Given,

Height of ceiling in bedroom = 10 feet

This is 2/3 height of living room ceiling.

Let,

x be the height of living room ceiling.

2/3 of x = 10

$\frac{2}{3}x=10$

Multiplying both sides by 3

$3*\frac{2}{3}x=10*3\\2x=30$

Dividing both sides by 2

$\frac{2x}{2}=\frac{30}{2}\\x=15$

The height of living room ceiling is 15 feet.

Wyatt's room is a rectangle with a perimeter of 40 feet.the width of the room is 8 feet.what is the length

sergij07 [2.7K]

Let's draw a diagram of this room so it's easier to solve. (see the image I've included)

The perimeter is the length of all of the sides of the rectangle, so
8 + 8 + x + x = 40
Simplify
16 + 2x = 40
Subtract 16 from both sides
2x = 24
Divide by 2 on both sides
x = 12

The length of the rectangle is 12.
