Answer:
10 minutes
Step-by-step explanation:
Let's use the variable x for the amount of coins.
The first machine can sort x coins in 15 minutes, so its speed is x/15 coins/minute.
The second machine can sort x coins in 30 minutes, so its speed is x/30 coins/minute.
If we sum the speeds, we have that the speed will be:
speed = (x/15) + (x/30) = (2x + x)/30 = 3x/30 = x/10
The total speed can sort x/10 coins per minute, that is x coins in 10 minutes.
Answer:
(13.8,1.42) (18,3.7)(16.7,3.21) and so on REMEMBER ITS (X,Y)

Answer:
B is your answer.
Step-by-step explanation:
Depends on 18/36 = 72/444, because 444 doesn't make sense at all. None of the others are equivalent. If it's 72/144 then this is the answer
Hope this helps.
Answer:
The correct answer is A) x = 1/4y^2
Step-by-step explanation:
Because the parabola opens to the side, we know that this is an x = equation. This allows us to eliminate both C and D.
Then we can determine that A is the correct answer due to the fact that it opens to the right. Negative lead coefficients always open to the left, so it could not be B

there is one and the other you just put in word form
