Answer: x=2
both 3 and 9 share the same x axis
Answer:
Step-by-step explanation:
<u>Given:</u>
- Speed of the wind = 3 mph
- Speed in calm weather = x
- Speed with the wind = x + 3
- Speed against the wind = x - 3
<u>We know that:</u>
- distance = time*speed or
- time = distance / speed
<u>We have equal time in both cases so comparing d/s ratios:</u>
<u>Solve for x:</u>
- 56(x - 3) = 30(x + 3)
- 56x - 168 = 30x + 90
- 56x - 30x = 90 + 168
- 26x = 258
- x = 258/26
- x ≈ 9.92
<u>The speed with the wind is:</u>
It is there is nothing else that match it so it is 4
1) How many weeks will Jake and Seth be equal? set the equations equal to each other and solve for x:
5x + 85 = 20x + 40
45 = 15x
<u><em>x = 3 weeks</em></u>
2) How much money will that be? plug x = 3 back into the equation to solve for y:
Jake: 5(3) + 85 = $100
Seth: 20(3) + 40 = $100
<u><em>answer is $100</em></u>
