In jerome's physics class, he had to solve the equation 40 = 12mv2 for m. each step of his work is shown below.

use the drop-down menus to explain each step.

clear check
given equation: 40 = 12mv2

step 1: 40v2 = 12m
on both sides of the equation.

step 2: 80v2 = m
on both sides of the equation.

i need answer asap like fast plaese by the morning or before 9: 00 you very much

Step-by-step explanation:

I think you mean 1/2 for 12. I will assume so

40 = (1/2) m v^2                Multiply both sides by 2

40*2 = (1/2)*2  *m * v^2    Combine the 2s cancel.

80 =  m * v^2                    Divide by v^2

80/v^2 = m * v^2/v^2       Cancel

80/v^2 = m

Since I don't have the drop down menus, you'll have do the matching.

answer: the value of x is 7cm

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
