Estimate the average by first rounding to the nearest 1,000:

1,000 2,300 2,600

1966.666667 or 2000

Step-by-step explanation: (1000+2300+2600) all of that divided by 3 gives you 1966.66667 which rounds to 2000 as the nearest 2000

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20
