Step-by-step explanation:
1)ab-c
=2(3)-4
=6-4
=2
2)6c-2b
=6(4)-2(3)
=24-6
=18
3)a+b-c+5
=2+3-4+5
=10-4
=6
5)7c-2a
=7(4)-2(2)
=28-4
=24

Answer:
13, 19, 73, 89
Step-by-step explanation:
Prime numbers only have two factors, 1 and itself.
When Anne Betty and Cynthia compared the amount of money each had, they discovered that Anne and Betty together had $12 Betty and Cynthia together had $18 and Anne and Cynthia together had $10.
<span>Who had the least amount of money? and how much was it?
a +b = 12
b + c = 18
a + c = 10
So what I did is simple XD A logical guess and check. I started with a = 1, but that was to little. And also didn't match up. So I kept going up and got a = 2, b = 10, and c = 8</span>
