In(x) =5
it's base is e
so x = e^5 is the answer
2(-2y+8)
-4y+16
Therefore the answer is:
-4y+16
I think the answer is the last one
6/1 ÷ 3/4
= 6/1 × 4/3
= 24/3
= 8
V = s/t
now, t is equal for both cases so we write these 2 equations:
440/(Vp+Vw) = t
and
340/(Vp-Vw) = t
Now again, since t is equal for both cases we can make these 2 equations equal to eachother.
440/(Vp+25) = 340/(Vp-25)
(Vp - 25)*44=34*(Vp+25)
44Vp - 1100 = 34Vp + 850
10Vp = 1950
Vp = 195
Answer is 195mph
