Question

a plumber charges $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. step 1: which operation should be performed to isolate the variable term? apply the subtraction property of equality. which value do you need to subtract? 130 56 214

Explanation:

Step1: Identify the equation

The equation is \(130 + 56x = 214\). To isolate the variable term \(56x\), we need to get rid of the constant term on the left side that is added to \(56x\).

Step2: Determine the subtraction value

The constant term added to \(56x\) is \(130\). According to the subtraction property of equality, we subtract \(130\) from both sides to isolate the variable term. So the value we need to subtract is \(130\).

Answer:

The value to subtract is \(130\) (from the options, it's the option with "130").
