Let the distance of the first part of the race be x, and that of the second part, 15 - x, then
x/8 + (15 - x)/20 = 1.125
5x + 2(15 - x) = 40 x 1.125
5x + 30 - 2x = 45
3x = 45 - 30 = 15
x = 15/3 = 5
Therefore, the distance of the first part of the race is 5 miles and the time is 5/8 = 0.625 hours or 37.5 minutes
The distance of the second part of the race is 15 - 5 = 10 miles and the time is 1.125 - 0.625 = 0.5 hours or 30 minutes.
8, 8 2/7, 26/3, 8.8
(You have to change 8 2/7 to 8.28 and 26/3 to 8.66
Okay, to solve this we simply find 75% of the carton of paper, because 100%-25% = 75%
0.75(27) = 20.25
The carton of paper costs $20.25
Answer:
4 T-shirts and 5 long sleeves shirts.
Step-by-step explanation:
T-shirt cost =$10
Long sleeve shirt cost = $15
Total number of shirts = 9
Total number of T-shirts = 4
Cost of 4 T-shirts = 4 × 10 =$ 40
Total number of long sleeve shirt = 5
Cost of 5 long sleeve shirt = 5 × 15 =$ 75
Verification:
75+40 = $115 proved!
