Can someone help me and explain the equation

Answers

Answer 1

Answer:

Answer:

Jason would have to work 60 hours.

Step-by-step explanation:

The equation you would use would be 450 + 12.50t = 1200.

1200 is the money needed, 450 is a constant factor, but the 12.50 changes depending on how many hours Jason works.

You will have to use inverse operations so you would go 450 + 12.50t - 450 = 1200 - 450. That equals 12.50t = 750. Then you divide 12.50 by 750 because 12.50t is multiplying. 750 ÷ 12.5 = 60. So Jason has to work 60 hours!

If this helped I would appreciate it if you marked me Brainliest. thank you and have a nice day!

Step-by-step explanation:

if y=2 then x=6, 2x3=6 ...if you multiple y with 3..you will get the answer of x

in that equation above..it will get x=3y...but there is no answer for it..so, you can convert it to, y=1/3x
