Need help with these 6 problems!!! Please help due today (do not answer if you don’t have the Answer) you don’t need to show work just provide me with the answers

7) m = 7

8) k = 15

9) a = -12

10) x = 1

11) n = 4

12) r = 11

Step-by-step explanation:

Solving all the questions step by step!

7) 1 = 6+m/12

8) 8 = 3 + k/3

9) -4(-8+a) = 80

10) 8(x-1) = 0

11) n/2 - 1 = 1

12) 1 = r-3/8

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.
