Answer:
w=35, L = 17
Step-by-step explanation:
the perimeter is all sides added together to total 104. so,
2L + 2W= 104
the width is one more than twice it's length, so W = 2L + 1
plug that into first equation.
2L + 2(2L+1)=104
distribute:. 2L + 4L + 2= 104 and continue to solve for L
6L + 2= 104 subtract 2 from both sides.
6L = 102, divide both sides by 6
L = 17. so the length is 17 ft. now use that number to put it in our equation for width, W= 2L + 1
W= 2(17)+1
W = 35
bearing in mind that a solution to a system of equations is where their graph intersect or meets, Check the picture below.
Answer:

Answer:
Step-by-step explanation:
Sally Jonas worked hours is
Monday - 8hours
Tuesday - 7hours
Wednesday - 8hours
Thursday - 10hours
Friday - 8hours
Total work hour = 8 + 7 + 8 + 10 + 8
Total work hour = 41 hours
Rate of pay = $4.95 / hour
So, the total pay for a week is
Total pay = total work hour × pay rate
Total pay = 41 × 4.95
Total pay =$202.95
