the basement has an area of 864 square feet. the width of the basement is two thirds its length. What is the length of the basem
Leno4ka [110]
A = 864
w = 2/3l

A = lw

Plug in what we know:

864 = l(2/3l)

Multiply:

864 = 2/3l^2

Divide 2/3 to both sides or multiply by its reciprocal, 3/2:

864 * 3/2 = l^2

2592/2 = l^2

1296 = l^2

Find the square root of both sides:

l = 36

So the length of the basement is 36 feet.

Vedmedyk [2.9K]
Go step by step

23 is decreased by : 23 -

The product of 44 and an unknown number

Let x represent the unknown number
And Product means multiplication

The product of 44 and an unknown number : 44x

Equals 199 : = 199

Now, put that all together

23 - 44x = 199

Now, begin to solve

Subtract 23 on both sides of the equation

-44x = 176

Divide both sides of the equation by -44 to isolate x

x = -4

The unknown number is -4
