Let X represent the number of pennies.
Let Y represent the number of nickels.
We know that X + 5Y = (Y + 5X) + 80.
4Y = 4X + 80
Y = X + 20
Hence, the difference between the number of pennies and the number of nickels is 20.
She will pay the same rate.
The answer is H) 0.75
all you do is divide 4.5 by 6 and you'll get 0.75
You add the left side 2/7+2/7+2/7= 6/7
You add the right side 1/2+1/2+1/2+1/2+1/2+1/2= 6/2 and that equal 3 when simplified.
Now you multiply 6/7 * 3 =2.5 Letter D
Answer:
Step-by-step explanation:
The values of a, b, c, are:
- a is whatever is in front of term (including sign)
- b is whatever is in front of term (including sign)
- c is the constant term (including the sign)
So for , we clearly see that a is -3, b is 36, and since there is no constant term, c is 0
