Team one had twice as many workers as team two. as a result of increased productivity the number of workers in team one was reduced by 5 and the number of workers in team two was reduced by 2. how many workers are there in each team now if there are 7 more workers in team one?

15 workers in Team 1 and 8 in Team 2.

Step-by-step explanation:

Let the number of workers that were  in team 2 = x, then the number in Team  1

would have been 2x.

So later we had 2x - 5 workers in Team 1 and x - 2 in Team 2.

Now there are 7 more workers in Team 1 so we have the equation

2x - 5 - (x - 2) = 7

x - 5 + 2 = 7

x = 10 .

So now there are 20 - 5 = 15 workers in Team 1 and 10 - 2 = 8  in Team 2.

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.
