Phil ate 2/5 of a pizza. caroline ate 1/4 of a pizza. how much did they eat in all? a) 1/3 pizza b)2/9 pizza c) 13\20 pizza d) 1 1/3

2/5 + 1/4 = 8/20 + 5/20 = 13/20

c) 13/20 pizza

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.
