12 years old

Step-by-step explanation:

Take 51 and 39 and subtract them.

51-39=12

step-by-step explanation:

if x = 2 you have to find x to finish the problem

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
