First, add 2 to both sides. You should have 3/2x=21. Multiply both sides by 2 which gives you 3x= 42. Divide by 3 and you have x=14
Well, you didnt exactly give me enough information to do the problem, but here it goes;
0.125 is a decimal, and as a fraction it converts to 1/8. Therefore, depending on the original unit, it could be 1/8 of a cup.
V = pi x R^2 x height
V= pi x 6^2 x 12
V= 432 pi (m^3)
X+y/2=1
-2+6/2=1
-2 + 3 =1 true
⇒ ( -2, 6) is the solution
