Antonio ran 129 laps at the park. Alan ran 20% more than that. how many laps did Alan run
Answer:
154.8
Step-by-step explanation:
20% is equal to 20/100= 0.20. So, 0.20 multiplied by 129 will give you 20% of 129 which is 25.8. If Alan ran 20% more then you add 25.8 to 129 which gives you an answer of 154.8.
Equation: 20/100= 0.2
0.2* 129= 25.8
25.8+129= 154.8
Alan ran 154.8 laps.

Answer:
27 Liters

Evaluate the expression when y= 7 and x = 9.
x + 4y
Answer:
[1] 9x - 4y = 7
[2] x - 4y = -17
[2] x = 4y - 17
// Plug this in for variable x in equation [1]
[1] 9•(4y-17) - 4y = 7
[1] 32y = 160
// Solve equation [1] for the variable y
[1] 32y = 160
[1] y = 5
// By now we know this much :
x = 4y-17
y = 5
// Use the y value to solve for x
x = 4(5)-17 = 3
Step-by-step explanation:
Answer:
9+4(7)
Step-by-step explanation:
Start by replaceing y with 7
Do the same with x
