The simpliest way to do this is to turn both fractions into decimals

7/10 goes to 0.7 and 2/5 goes to 0.4

then the equation would be 0.7x + 20 = 0.4

hope I've helped!

Answer:

B. 1,188 cubic units

Step-by-step explanation:

First find the area of the base

A = 1/2b*h (this would only be half the base so our formula would be)

A = b*h (Now enter values)

A = (9)(6)

A = 54 (now plug this into the volume formula)

V = Ab * h

V = (54)(22)

V = 1,188 cubic units
