Answer:

V = 10

Step-by-step 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 = \frac{R - 2T}{3}

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

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

V = 30 / 3 = 10

Answer:

V = 10

Step-by-step 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

Solve -6f + 13 = 2f - 11​
igor_vitrenko [27]

Answer:

f = 3

Step-by-step explanation:

Solve for f:

13 - 6 f = 2 f - 11

Subtract 2 f from both sides:

13 + (-6 f - 2 f) = (2 f - 2 f) - 11

-6 f - 2 f = -8 f:

-8 f + 13 = (2 f - 2 f) - 11

2 f - 2 f = 0:

13 - 8 f = -11

Subtract 13 from both sides:

(13 - 13) - 8 f = -13 - 11

13 - 13 = 0:

-8 f = -13 - 11

-13 - 11 = -24:

-8 f = -24

Divide both sides of -8 f = -24 by -8:

(-8 f)/(-8) = (-24)/(-8)

(-8)/(-8) = 1:

f = (-24)/(-8)

The gcd of -24 and -8 is -8, so (-24)/(-8) = (-8×3)/(-8×1) = (-8)/(-8)×3 = 3:

Answer:  f = 3
