Am going to presume you want it solved.
Please pardon my presumption
7 - (2/3)x < x - 8, Take all the x to one side of the inequality
-(2/3)x-x < - 8 -7
-(5/3)x < - 15 Divide both sides by -5/3 and inequality sign changes
x > (-15)/(-5/3)
x > 15 * 3/5 . 5 into 15 is 3.
x > 3*3
x > 9
1. Use the Pythagoras theorem
13^2 = x^2 + 5^2
solve for x and youll get the height of the roof.
2. let x = length of the rpoe)-
x^2 = 9^2 + 12^2
3. Pythagoras again
20^2 = x^2 + 12^2
The volume of a pyramid is 1/3 the volume of the cube mentioned in the question since it fits exactly inside it. So multiply 49*3 = 147 cubic feet
