Answer: 47/6
Step-by-step explanation:
-2 1/3 - (-10 1/6)
= -7/3 + 10 1/6

The UNIT rate of a changing quantity is the amout it changes per single increment of time
Answer: 3 more days after the first 7
Step-by-step explanation:
6(7)=42
60-42=18
18/6=3
Equation 1. N+D=500
equation 2 5N+10D=3000
This is for equation 1
N=500-d
Substitute into equations 2 and solve for D
5N+10D=3000
5(500-D)+10D=3000
2500-5D+10D=3000
5D=500
D=100
Lets go back the equation 1
N=500-D
N=500-100
N=400
there are 400 Nickles and 100 Dimes
