Movie Theatre A has a popcorn machine with a 120-gallon capacity. It sells 7 gallons of popcorn per hour. Movie Theatre B has a popcorn machine with a 150-gallon capacity. It sells 9 gallons of popcorn per hour. Write and solve an equation to show when the two popcorn machines will have the same amount of popcorn left.(1 point)

120x−7=150x−9 ; x=15
120 x minus 7 equals 150 x minus 9, ; , x equals 15

120+7x=150+9x ; x=−15
120 plus 7 x equals 150 plus 9 x, ; , x equals negative 15

120−7x=150−9x ; x=15
120 minus 7 x equals 150 minus 9 x, ; , x equals 15

120−7x=150−9x ; x=10

The correct equation to use is 120 - 7x = 150 - 9x, where x represents the number of hours that have passed.

Simplifying the equation, we get:

2x = 30

Solving for x, we get:

x = 15

Therefore, the two popcorn machines will have the same amount of popcorn left after 15 hours.

The correct response is:

120 - 7x = 150 - 9x ; x = 15
1: 12x+210=15x+180

2: 100-3x=150-5x

3: 180-20x=140-16;x=10

4: 120−7x=150−9x ; x=15

5: 50+20x=100+10x; x=5; after 5 days the prices are equal

I hope this helps
the answer to number 4 is: 92 + 16x = 104 + 13x
