Which expression represents the total cost for Ari to rent a bike for b hours and Meg to rent a scooter for s hours? A. 9+10
B. (9+b) + ( 10+s)
C. 9 + 10 ×b + s
D. 9b + 10s

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

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.
