Answer:
Step-by-step explanation:
We first need to figure out how much money Jackie has since Pilar has the same amount of money, but in different coins. Jackie has 24 dimes and 13 quarters, so the amount of money is $2.40 + $3.25 = $5.65; therefore, Pilar has $5.65 also. In order to determine how many nickels and quarters Pilar has, we have to have a system of equations. It's up to us to write the equations we need to solve this. The first equation has to do with the NUMBER of coins Pilar has, the second has to do with the VALUE of each coin. We know that Pilar has only nickels and quarters and that she has a total of 53 coins. So the NUMBER equation is
n + q = 53
The VALUE equation relates how much each coin is worth to the total amount of money it equals:
.05n + .25q = 5.65.
Go back to the first equation and solve it for either n or q. I solved it for n:
n = 53 - q
Plug this into the second equation in place of n now to get:
.05(53 - q) + .25q = 5.65 and
2.65- .05q + .25q = 5.65 and
.20q = 3 so
q = 15. This means that there are 15 quarters. If there are 15 quarters, then there are
n + 15 = 53 nickels and
n = 38 nickels.

Answer:
A) Cost is the dependent variable
B) $75.00
Step-by-step explanation:
We are given the following information in the question:
Cost of renting a snowmobile for 5 hours = $37.50
a)
If c represents the cost and h represents the hours. then cost is the dependent variable as it depends upon the number of hours for which the snowmobile is rented.
b)
Cost of renting a snowmobile for 1 hour =
Cost of renting 2 snowmobiles for 5 hours =
Answer:
-3/2
Step-by-step explanation:
(9/10) / (-3/5).
Divisions between fractions is the same as cross multiplication, by that I mean the following
(a/b) / (c/d)= (a*d) / (b*c)
So, our expression is the same as the following= 9*5 / (-3*10) = -45/30= -3/2
