The sum of the 3 outside angles of a triangle equal 360 degrees.

Add the equations together to equal 360:

x+8 + x +20 + 2x +12 = 360

Combine the like terms on the left side of the equal sign:

4x + 40 = 360

Subtract 40 from both sides:

4x = 320

Divide both sides by 4:

x = 80

Luigi is an urban planner. As an independent contractor, he charges a $140 fee plus $25 per hour for

Anuta_ua [19.1K]

Answer:

Function: $y=140+25x$

Amount earned for 10 hours of work: $\$390$

Step-by-step explanation:

Let be "x" the number of hours worked on a project and "y" the total amount Luigi charges for a project.

Based on the data given in the exercise, you can identify that:

$140 is a fixed amount.
For each hour worked on the project, Luigi charges $25. This can be expressed as: $25x$

Then, the total amount he charges for a project is the sum of $140 and $25x$ . This can be represented with the following function:

$y=140+25x$

To calculate the amount of money earned for 10 hours of work, you must substitute $x=10$ into the function and evaluate. Then:

$y=140+25(10)\\\\y=390$
