Answer:
We must think that the cars are traveling 630 miles in six hours.
Their combined speeds are x and x+25.
distance = velocity * time
Since, velocity = distance / time
(x + x + 25) = 630 / 6
2x + 25 = 105
2x = 80
So x = 40 mph and the other car's velocity is 65 mph.
Step-by-step explanation:
That would be 140
10% is basically the same thing as 1/10. So if you want to find the answer, do the opposite of 1/10, which is 10.
That way, you can get 14 * 10 = 140
Answer:
Step-by-step explanation:
In order to solve this problem, lets take the two terms in the binomial (4x and -3) and, for each one, multiply them by each term in the trinomial (2x^2, -7x, and 1):
Let's combine like terms to get our final answer:
