james and mark are delivering newspapers. if james delivers 130 papers in one hour and Mark delivers 210 papers in three hours, how long will it takes both of them working together to deliver 1000 newspapers?

James deliver newspaper in 1 hour=130

Marks deliver newspaper in 1 hour= 210/3=70

so lf they work together to deliver 1000 newspaper they take 130+70=200. 1000/200=5.

so they take 5 hours to deliver 1000 newspaper.

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.
