A plumber charges $17 to visit a client's home, plus an additional $36 per hour. What is the

Because this is a linear problem, I'd use the slope-intercept formula:

y = mx + b

where

m = slope (rise/run)

y = dependent value

x = independent value

b = constant value

Because the plumber charges $17 upon arrival, it is our constant. The $36 is our slope (<em>per</em><em> </em><em>hou</em><em>r, per minute, per etc.</em> is generally a give away). Additionally because the total cost of the plumber's visit depends on how long s/he stays at a client's home, the $89 is our y value. Therefore the equation should look like this:

89 = 36x + 17

Solve for x by subtracting 17 from both sides of the equation then dividing by 36.

72 = 36x

2 = x

The plumber spent two hours at his/her client's home.

Answer:

I believe the duration for $89.00 is 2 hours

Step-by-step explanation:

We start off with the $17 dollars and calculate 36.00+36.00 for a total of $89. Therefore, (120 mins)/60=2 hours.

Hello there! :)

Answer:

\boxed{b>8}\checkmark

<h2><u><em>*****The answer should have a GREATER THAN SIGN AND POSITIVE TOO!*****</em></u></h2>

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

PEMDAS

Order of operations

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

Left/Right

First, you add by 4 from both sides of an equation.

b-4+4>4+4

Then, you add numbers from left/right.

4+4=8

\boxed{b>8}, which is our final answer.

Hope this helps you!
