Hey!
You have to divide the total amount she has by the surface area.
Surface area = 2(wl+hl+hw)
That gives you:
The surface area is 126 ft. Now divide the total amount she has by the surface area.
<em>That means she can cover 9 boxes</em>
Answer: 133 windows
Step-by-step explanation:
Step 1: 38/2=19
Step 2: 19*7=133
150x4 is 600 volume for the answer
The number that twice the sum of it and negative seven is eight is 11.
<h3>How to find the number ?</h3>
Twice the sum of the number and negative seven is eight. The number can be found as follows:
let
the number = x
According to the word expression, twice the value of the addition of x and minus seven is equals to 8. Hence, we will find the value of x in the equation formed from the words expression.
The variable x is the required number.
Therefore,
2(x + (-7)) = 8
2(x - 7) = 8
open the brackets
2(x - 7) = 8
2x - 14 = 8
add 14 to both sides of the equation
2x - 14 = 8
2x - 14 + 14 = 8 + 14
2x = 22
divide both sides by 2
x = 22 / 2
x = 11
