Question

Use the formula R=3V+2T to find V when R=40 and T=5

Answer 1

V = 10

Explanation:

to find V, you must make the equation V = ......

original equation is

R = 3V + 2T

first subtract 2T from both sides

R - 2T = 3V

now divide by 3

V =
`(R - 2T)/(3)`

now plug in the numbers for R= 40 and T= 5

V = (40 - 2(5)) / 3

V = 30 / 3 = 10

Answer 2

V = 10

Explanation:

Plug in give information

40 = 3V + 2×5

40 = 3V + 10 we want to get V by itself so subtract 10 from both sides

30 = 3V Divide both sides by 3

10 = V
