A. 91.5
B. 57.3
C. 2.8175
D. 23

Answer 1

12+0.35x=20.05

Since 12 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 12 from both sides.
0.35x=-12+20.05

Add 20.05 to -12 to get 8.05.
0.35x=8.05

Divide each term in the equation by 0.35.
(0.35x)/(0.35)=(8.05)/(0.35)

Cancel the common factor of 0.35.
x=(8.05)/(0.35)

Divide 8.05 by 0.35 to get 23.
x=23
