Answer:
It is correct according to the laws
Answer:
5 or 6
Step-by-step explanation:
So I did it in a different way than shown in rsm classes. I said that the speed was x-2 and x.
then I said the distance was 6 and 15. If the time taken was 1 hour more, then we can come up with this equation:
Since the time is 6/x-2 or 15/x
15/x-6/x-2=1
multiply everything to get a common denominator then cancel it out to get
(15x-30)-6x=x^2-2x
11x-30=x^2
x^2-11x+30=0
(x-5)(x-6) is factored form.
so x=5 or x=6. this means that the speed of the boat is either 5km/h or 6 km/h
Answer:
-8p^4+12p^3+4p^4-8p^2+3p^2
=-8p^4+4p^4+12p^3-8p^2+3p^2
=-4p^4+12p^3-5p^2
=p^2(-4p^2+12p-5)
note: If you have to solve for X
there are steps according to formula
Answer:
r=.57
Step-by-step explanation:
The unit rate is found by dividing the amount earned by the number of hours worked. So
unit rate = amount earned / number of hours worked = 51 / 6 = $8.5 / hour
