The weight of Euclid is 10.625 pounds, and the weight of Riemann is 21.25 pounds.
- <em>Let the current weight of Euclid = x</em>
- <em>Let the current weight of Pythagoras = T</em>
- <em>Let the January weight of Pythagoras = y</em>
The expression that represents the given scenario is written as;
- when Pythagoras lost 13 pounds: T = y - 13
- when Pythagoras gains 1.2 times Euclid's weight: = T + 1.2x
when Pythagoras weight is 1/4 pound less than weight in January:
T + 1.2x + 0.25 = y
y- 13 + 1.2x + 0.25 = y
1.2x - 12.75 = 0
Euclid's weight is calculated as follows;
1.2x = 12.75
The weight of Riemann is calculated as follows;

Answer:
0
Step-by-step explanation:
Thus the expression is 0.15x.
Given,
A reasonable tip for some is 15% of the subtotal.
We need to write an expression that would represent how much tip you should leave if x represented the subtotal.
<h3>How to write the percentage of a quantity?</h3>
Let the quantity be 100.
5% of 100 = 5/100 x 100 = 5
10% of 100 = 10/100 x 100 = 10
50% of 100 = 50/100 x 100 = 50
We have,
Subtotal = x
Tip = 15%
Write the expression for 15% of x
15% of x
= 15/100 x (x)
= 0.15x
Thus the expression is 0.15x.
