paint costs $2.75. Jared spent $22.25 in
all. How many cans of black (b) and how
many cans of red (r) did hé buy?
r+b=7
3.75r+2.75b=22.25

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

yes

step-by-step explanation:

yes

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.
