So first I would say, what if all of them were dimes, how far away would it be from $14?
So 92 coins * 10 cents = $9.20
So it's 4.80 dollars away from 14 dollars.
So if we were to switch one to a quarter, it would increase by 0.15 cents.
So we want to see how many increases we need to reach 4.80 dollars more.
4.80/0.15 = 32
So there are 32 quarters and 60 dimes.
Answer:
a - 13/30
Step-by-step explanation:
2/5 +x = 5/6
2/5 + x -2/5 = 5/6 - 2/5
x = 13/30
5(2x^2 - 5x - 3) = 5(2x + 1)(x - 3)
hope this helps :)
So your goal is to set it equal to Y, so you have to start by subtracting k and you get t-k, then you have to get rid of the fraction by multiplying both sides by the denominator (n), so then you get n(t-k) and the only thing left is to divide by the e, and you get 4
