Answer:
1. 8
Explanation: 5x + 20(.50)=50
5x + 10=50. Now do 50-10 to get 40. So,
5x=40. Now divide 40/5 to get 8.
2. .5
5(8) + 20x=50. Now do 5*8
40 + 20x=50. Now, 50-40 to get
20x=10. And divide 10/20 to get .5
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
