Answer:
x=3/2, y=10. (3/2, 10).
Step-by-step explanation:
2x-y=-7
4x-y=-4
--------------
-2(2x-y)=-2(-7)
4x-y=-4
---------------------
-4x+2y=14
4x-y=-4
-----------------
y=10
2x-10=-7
2x=-7+10
2x=3
x=3/2
Answer:
14 nickels
7 dimes
Step-by-step explanation:
1. find out how many dimes there has to be to get $1.40
1 dime= .10
1.40/.10=14 dimes
14/2=7
so there are 7 dimes
since a nickel is half the amount of a dime there will be twice as many to make up the other half which is $0.70
.70/.05=14
there are 14 nickels
proof:
$0.10(7)+$0.05(14)= $1.40
hope this helps!
