Answer:
x = 4, y = 3/5
Step-by-step explanation:
3x - 5y = 7
2x + 5y = 13
add the equations
5x = 20
x = 4
plug in x for one of the equations
2(5) + 5y = 13
10 + 5y = 13
5y = 3
y = 3/5

Answer:
32 coins
consider the value of a group of coins
Step-by-step explanation:
The coins are in equal numbers, so they can be considered as a group. The value of one group of 4 coins is ...
1¢ + 5¢ + 10¢ + 25¢ = 41¢ = $0.41
Then the number of groups (g) of coins is ...
$3.28 = $0.41×g
g = $3.28/$0.41 = 8
There are 8 groups of coins. Each group has 4 coins, so there are ...
(8 groups)×(4 coins/group) = 32 coins
