SashulF [63]

If at 10 Am there were

10 AM.......................12 people

-4c+5d = 14<br> -40+ 3d= 8

solmaris [256]

Answer:

d = 3 c= 1/4

Step-by-step explanation:

Eq. 1) -4c + 5d = 14

Eq. 2) -4c + 3d = 8 ( the written Eq. says 40 but I am guessing it's 4c )

subtract Eq. 1 and Eq. 2

2d=6

d=3

plug 3 in for d in Eq. 1

-4c + 5(3) = 14

-4c + 15 = 14

-4c = -1

c = 1/4
