Sharon has some one-dollar bills and some five-dollar bills. she has 14 bills. the value is 30 dollars. solve a system of equations using elimination to find how many of each kind of bill she has.

4 $5 bills and 10 $1 bills

Step-by-step explanation:

We know she has less than 6 5 dollars bills because 6x5=30 and that is not enough bills. So take it down to 4 $5 bills and that’s 20 dollars +10 and you have 30 dollars using 14 bills

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
