Answer:
1. x = 8
2. y = 1/2
Step-by-step explanation:
1. Plug the function
5x + 20(0.50) = 50
= 5x + 10 = 50
Subtract 10 from both side
= 5x = 40
Divide 5 on both sides
= x = 8
2. Plug in the function
5(8) + 20y = 50
= 40 + 20y = 50
Subtract 40 on both sides
= 20y = 10
Divide 20 both sides
= y = 10/20 | 1/2

Answer && Step-by-step explanation:
7 yards == 4/4
by simple arithmetic remove 3/4 from 7 until you can no longer obtain 3/4 from it
7 => 6*1/4
6*1/4=>5*2/4
5*2/4=>4*3/4
4*3/4=>4
4=> 3*1/4
3*1/4=>2*2/4
2*2/4=>1*3/4
1*3/4=>1
1=>1/4
1/4 remains and 9 bows were made
