Let one piece of the rope be x
Let the other piece of rope be x + 5
These two pieces put together will make 20 feet.
So we say:
x + (x +5) = 20
What is x? We expand the equation.
x + x + 5 = 20
x + x = 20 - 5
2x = 15
x = 7.5
The shorter piece is therefore 7.5 feet.
The longer piece is 7.5 + 5 = 12.5 feet.

Answer:
4.5
Step-by-step explanation:
This problem is set up in such a way that you take 1/10 of a number and equate it to 0.45
1/10 of x = 0.45 or
1/10 * x = 0.45 Multiply both sides by 10
1/10 * x * 10 = 0.45 * 10 Combine
x = 4.5
<h3><u>Question:</u></h3>
Aubrey's dinner cost $85 . She tips the waitstaff 30% for excellent service. How much does Aubrey tip the waitstaff?
<h3><u>Answer:</u></h3>
Aubrey paid $ 25.5 to the wait staff
<h3><u>Solution:</u></h3>
Given that, Aubrey's dinner cost $ 85
She tips the waitstaff 30% for excellent service
We have to find the amount paid as tip to wait staff
Cost = $ 85
Tip = 30 %
So the tip amount paid is 30 % of 85
<h3><u>Find out 30 % of 85</u></h3>

Thus Aubrey paid $ 25.5 to waitstaff
