Since she makes $10 per hour and is already one unit, we just divide $150 by $10 which is 15. Thus the number of hours it will take her is 15 hours.
They had 30 I know this because I did 37 times 32x divided my y plus 15

Explanation:</h2>
The complete question is attached below. In order to solve this problem, we'll use a graphing tool. First of all, we'll say that the LHS is a linear function and the RHS is another linear function, so for each case, we'll have:

For each graph,
will be drawn in red while
will be drawn in blue.
Case 1:

So by equating both equations:

By using graphing tool we get a point of intersection at which the x-value is the solution to our equation. So:
<u>Solution:</u>

See First Figure below.
Case 2:

Applying a similar method as in case 1.
<u>Solution:</u>

See Second Figure below.
Case 3:

Answer:
Step-by-step explanation:
<u>As per the diagram we got:</u>
<u>As FH = 7x + 4 and EH = 9x - 2, we solve the following equation for x:</u>
- 7x + 4 = 9x - 2
- 9x - 7x = 4 + 2
- 2x = 6
- x = 3
<u>So each segment is:</u>
<u>Therefore</u>:
<u>So the variables are:</u>
I think the correct answer is 17
