US roof regulations state that asphalt tiles can only be used for roofs with a maximum gradient of 0.17. The roof shown in the diagram has width 7 m and rise 1.6 m. Find: a the roof run b the roof gradient. Roof rise Roof run c Determine whether the roof satisfies the requirements for using asphalt tiles. Justify your conclusion.

step-by-step explanation:

n=1.75+1.75

step-by-step explanation:

3.5/2=1.75

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
