To solve for n:
n/3+5=7
Subtract 5 from both sides.
n/3=2
Multiply both sides by 3.
n=6
Hope this helps! :)

the answer to the question
Answer:
94.6m³
Step-by-step explanation:
The diagram shown in this question is a trapezoidal prism.
The volume of a trapezoidal prism is calculated as:
L × H × (P + Q/2)
Where L = Length = 4m
H = Height = 4.3m
P = Base width = 8m
Q = Top width = 3m
The volume of the trapezoidal prism =
4 × 4.3 ×(8+3/2)
=4 × 4.3 ×(11/2)
= 94.6m³
Therefore, the volume of the trapezoidal prism to the nearest tenth = 94.6m³
128.79 *.30 =38.937
128.79-38.937=89.853
So with a 30% discount 128.79 is 89.853
15 is 60% of 25. 15/25 is equal to .6 or 60%
