Answer:
Step-by-step explanation:
Let the speed of current be x
<u>Speed of the boat in same direction as current is</u>
<u>Speed against the current is</u>
<u>Based on the given we get the equation for time</u>
<u>Solving for x</u>
- 6(10 - x) = 4(10 + x)
- 60 - 6x = 40 + 4x
- 6x + 4x = 60 - 40
- 10x = 20
- x = 2
The answer is 2 mph
First, find the slope of the line thru these 2 pts:
5-4
m = --------- = -1/2
2 -4
Use the slope-intercept formula y = mx + b:
5 = (-1/2)(2) + b. Then the y-intercept is 5 + 1, or 6: y = (-1/2)x + 6
Multiplying this entire result (3 terms) by 2 results in 2y = -x + 12, or
x + 2y = 12 (answer)
16-3p=2/3p+5
add 3p to each side
16 = 3 2/3 p +5
subtract 5
11 = 3 2/3 p
change to an improper fraction
11 = (3*3+2)/3 p
11 = 11/3 p
multiply by 3/11 on each side
11 * 3/11 = 3/11 * 11/3 p
3 =p
Answer:
the answer is 8/12 but simplified the answer is 2/3.
