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:
d the expression with the fractions three fifths minus one half is equal to the expression with the fractions six tenths minus five tenths is equal to the fraction one tenth
Step-by-step explanation:
Chris requires three fifths liter of paint to complete a poster. He has one half liter of paint. Which equation can be used to find the fraction of a liter of paint Chris still needs to complete the poster?
The fraction of a liter Chris requires to complete his painting is given as:
3/5 liter = 1/2 liter + x
x = 3/5 - 1/2
Lowest Common Denominator = 10
x = 6 - 5/10
x = 1/10
option d is the correct option.( the expression with the fractions three fifths minus one half is equal to the expression with the fractions six tenths minus five tenths is equal to the fraction one tenth)
