A plumber $130 to start a job plus $56 per hour. How many hours did she work if the total bill is $214? This problem can be modeled with this equation: 130+56x=214 which operation should be preformed to isolate the variable term?

Combine like terms by subtracting

Step-by-step explanation:

1.5

Step-by-step explanation: half an hour is 28 dollars. if he worked for 1 hour, it would be 186 +28 which was the left over amount of money to add up to 214, simply put, 1 hour and 30 minutes or 1.5 hours

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
