Answer:40
Step-by-step explanation:
100+10+10=3x
3x=120
Divide both sides by 3
X=40
Yes,
10 x 5 = 50
4 x 5 = 20
They both have equal multiples.
Answer:
c
Step-by-step explanation:
The volume (V) of a square based pyramid is calculated as
V = Ah ( A is the area of the base and h is the height )
Here V = 1350, thus
× 15²h = 1350 ( multiply both sides by 3 to clear the fraction )
225h = 4050 ( divide both sides by 225 )
h = 18 ft → c
