Answer: 8 ft
<u>Step-by-step explanation:</u>

Question is incomplete Let assume the Slope = 2
Answer:
Therefore the Equation of line is

Step-by-step explanation:
Given:
Slope = 2 ( Assumption )
y-intercept = -3
To Find:
Equation of Line in Slope-intercept form
Solution:
Equation of Line in Slope-intercept Form is given as

Where,

So, substituting Slope =2 and y-intercept = -3 in above we get
Which is the Required Equation of line
Therefore the Equation of line is

(1)
10(1+3x)=-20
Cross multiply.
10+30x=-20
Isolate x on one side. So you would subtract 10 on each side. and one side will cross each other out. leaving you with,
30x=-20-10
Subtract 10 from -20.
30x=-30
Divide each side by 30 to get x.
30x÷30=-30÷30
Therefore,
x=-1
(2)
-5x-8(1+7x)=-8
Cross multiply -8(1+7x)
-5x-8-56x=-8
Isolate all x's on one side. So you would add 8 on each side. and one side will cross each other out. leaving you with,
-5x-56x=-8+8
Add 8 to -8.
-5x-56x=0
Subtract -56x from -5x
-61x=0
Divide each side by -61
-61x÷-61=0÷-61
Therefore,
x=0
First find the hourly rate by dividing $187 by 11 hours. That yields $11 per hour. Now multiple the $11/hour rate by 8 hours of work resulting in $88.
