Step-by-step explanation:
Answer:
30x - 18
Step-by-step explanation:
6(5x - 3)
<em>Distribute the 6 to both monomials.</em>
6 * 5x = 30x
6 * -3 = -18
<em>Combine both final monomials.</em>
30x - 18
Answer:
Step-by-step explanation:
- Let the speed of the boat = b and the speed of the current = c
<u>Equations to reflect time, time = distance/speed:</u>
- 80/(b + c)= 5 ⇒ b - c = 80/5 ⇒ b + c = 16
- 80/(b - c) = 10 ⇒ b - c = 80/10 ⇒ b - c = 8
<u>Sum of the 2 equations above</u>
- b + c + b - c = 16 + 8
- 2b = 24
- b = 12
- c = 16 - 12 = 4
So the speed of the boat is 12 mph
The speed of the current is 4 mph
