the answer is 15 im pretty sure
Answer:
= 298/11
Step-by-step explanation:
3x + 5y = 2 | ×2 |
2x - 4y = 20 | ×3 |
6x + 10y = 4
6x - 12y = 60
____________--
22y = -56
y = -56/22
y = -28/11
3x + 5y = 2 | ×4 |
2x - 4y = 20 | ×5 |
12x + 20y = 8
10x - 20y = 100
_____________+
22x = 108
x = 108/22
x = 54/11
5x - y
= 5(54/11) - (-28/11)
= 270/11 + 28/11
= 298/11

Answer:
10:51
Step-by-step explanation:
Given that :
Distance from A to B = 130km
Departure time = 8 : 15
Average speed = 50 km/hr
Recall :
Speed = distance / time
Time = distance / speed
Time = (130 km) ÷ (50km/hr)
Time = 130 / 50
Time = 2.6 hours = 2 hours + (0.6 * 60) = 2 hours 36 minutes
Arrival time = (8:15) + (2 hours 36 minutes) = 10:51
Answer:
Answer 100
Step-by-step explanation:
so if they can pack 25 boxes in 2 hours then you can do 8/2 which would equal four then 4*25 to get 100. You would do the division of 8 by two because you have 8 hours and it take 2 for 25 boxes.
