Your answer:
20% of 28.35 is 5.67. 6.25% of 28.35 is 1.77. Add 28.35, 5.60, and 1.77 to get the final total of $35.79
No because the b in the equation y=mx+b is the first coordinate which DOES NOT go through origin (0,0)
Answer:
67.5 miles
Step-by-step explanation:
If x is the distance one way, then the time it takes when moving with the current is:
x = 15 t₁
The time it takes when moving against the current is:
x = 5 t₂
The total time is 9 hours:
t₁ + t₂ = 9
Substituting:
x/15 + x/5 = 9
4x/15 = 9
4x = 135
2x = 67.5
The total distance round trip is 67.5 miles.
