Answer:
Write a time equation, time = dist/speed
:
go time + return time = total time
d%2F16 + d%2F15 = 7.75 hrs
multiply equation by the least common multiple 240, cncel the denominators:
15d + 16d = 240(7.75)
31d = 1860
d = 1860/31
d = 60 km one way
total dist = 120 km
:
Check this, find the actual time each way
60/16 = 3.75 hrs
60/15 = 4 hrs
-----------------
total time 7.75 hrs

Answer:
Its a wrong i teaching 2*2=4 Cause 4+50=54 -Its a correct
Answer:
(x-3) and (x+3) I think
Step-by-step explanation:
We have the formula S= r * theta , where S is arc length , r is radius , and theta is central angle in radians
So AB= 4 * 45* π/180 = π units
To solve this problem, all you have to do is set the exponents equal to each other because the bases are the same.
2n=10
<em>*Divide both sides by 2*</em>
n=5
The answer is 5.
Hope this helps!
