Which would be used to solve this equation? Check all that apply.

p Over 3=12

subtracting 3 from both sides of the equation

multiplying both sides of the equation by 3

dividing both sides of the equation by 3

substituting 4 for p to check the solution

substituting 36 for p to check the solution

multiplying both sides of the equation by 3

substituting 36 for p to check the solution

Step-by-step explanation:

To determine the equation, you would "undo" the division by 3. The way you do that is to multiply both sides of the equation by 3.

Once you know the answer is 36, then you can check that by substituting 36 for p. (Some might call this "solution by guessing" if you were to start with this step.)

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
