It takes Ben 30 minutes to cut a long piece of wood into six pieces. How long does it take him to cut into nine pieces?
The answer is 48, can you please explain why?

45

Step-by-step explanation:

so since it take 30 minutes to cut 6 pieces, take 30 and divide it by 6 and you get 5 minutes for each piece. 5*9= 45 which is the total time

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.
