Answer:
62
Step-by-step explanation:
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
Its 1+20x because you would subtract 2-1-=1 and 35x-15x=20x im sorry this is the real correct answer
Answer:
1/2
Step-by-step explanation:
x + 9 = -15x = [1]
x - x + 9 = -15x -x = 1
9 - 1 = -16x
8 = 16x
8/16 = 16/16x
1/2 = x
Hope this helps
Can you rewrite the equation? It doesn’t make sense
