Answer:
3.6 mph
Step-by-step explanation:
The total distance was 6 mi. and the total time was 5/3 hr.
6 ÷ 5/3 = 6(3/5) = 18/5 = 3.6 mph
Option 1- y= 53x+10
Option 2- y= 55x
55x+10=53x
-53x -53x
2x=10
x=5
Answer:
Quarters = 20
Dimes = 14
Step-by-step explanation:
Dime = x = 10 cent = $0.1
Quarter = y = 25 cent = $0.25
x + y = 34 - - - (1)
0.1x + 0.25y = 6.40 - - - - (2)
From (1)
x = 34 - y
0.1(34 - y) + 0.25y = 6.40
3.4 - 0.1y + 0.25y = 6.40
3.4 + 0.15y = 6.40
0.15y = 6.40 - 3.40
0.15y = 3
y = 3 / 0.15
y = 20
x = 34 - y
x = 34 - 20
x = 14
Quarters = 20
Dimes = 14
