Answer and Step-by-step explanation:
Remember the formula for calculating volume is:
Volume = Area by height
V = A X h.
For a triangle the area is calculated using the formula:
Area = half of base by altitude
A = 0.5 X b X a.
So to calculate the volume of a triangular prism, the formula is:
V = 0.5 X b X a X h.
Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:
b = (c-3a)/2
Step-by-step explanation:
3a+2b =c
Subtract 3a from each side
3a-3a+2b =c-3a
2b = c -3a
Divide each side by 2
2b/2 = (c-3a)/2
b = (c-3a)/2
Answer:
C, sorry if wrong
Step-by-step explanation:
at most is either that number or less
so x<=72 would be the inequality
