9. y=9h+4

10. y=5r+10

11. y=4x+8

12. y=4n+9

Step-by-step explanation:

9. He gets 9 dollars per hour (h), and 4 dollars extra for gas.

So 9 dollars per hour plus 4 dollars for the gas

y=9h+4

10. Roses (r) are selling for 5 dollars each and there is a delivery fee of 10 dollars.

So 5 dollars per rose plus 10 dollar fee

y=5r+10

11. The tree increases by 4 feet per year (x), and it is already 8 feet tall.

So 4 feet per year plus 8 feet

y=4x+8

12. Each trophy (n) weighs 4 kilograms, and the box itself weighs 9 kilograms.

So 4 kilograms per trophy plus 9 kilograms for the box.

y=4n+9

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2
