Answer:
120 hours
Step-by-step explanation:
If it was 12 hours per week you multiply 12 by 10
(1.636, 14.545) simply plug in the y=4x+8 into the second equation and then solve
Expand 8(5-r)/5=-2r as indicated: 40 - 8r
----------- = - 2r
5
Multiply both sides by 5, obtaining 40 - 8r = - 10r
Combine like terms: 40 = - 2r
Divide both sides by -2: -20 = r
The solution to 8(5-r)/5=-2r is -20. Verify this by subbing -20 for r in the given equation.
2y-x=-8
2y=x-8
y=1/2x-4 is the slope intercept form
