Answer:
Step-by-step explanation:
Finding the percentage of the cost that is the tip means finding the percentage of the reduction or fall in price on the initial price.
The initial price of the shirt is $27
There was a reduction in price from $27 to $20. Reduction in price is determined by subtracting the new price from the original price. Therefore
Reduction in price(tip) = 27 - 20 = 7
To determine the percentage of the cost that is the tip, we will divide the tip by the initial cost and multiply by 100. It becomes
7/127 × 100
= 25.93%
Given:
Line a and line b
To find:
Which is the correct solution set for the graph.
Solution:
Here line a is on the line b.
So that a and b have same slope and same solution set.
For any graph of the line, the solution set is the points on the line.
Therefore the solution set is the infinite set of points on the line.
The correct solution set for the graph is infinite set of points on the line.
The pressure is 39 Pa if the volume is expanded to 168L and the pressure, P, of a gas varies inversely with its volume, V.
<h3>What is a proportional relationship?</h3>
It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
We have:
The pressure, P, of a gas varies inversely with its volume, V.
P ∝ 1/V
P = k/V
k is the constant.
If P = 126 Pa and V = 52 L
126 = k/52
k = 6552
P = 6552/V
Plug V = 168 L
P = 6552/168 = 39 Pa
Thus, the pressure is 39 Pa if the volume is expanded to 168L and the pressure, P, of a gas varies inversely with its volume, V.

2x - 3 = 11
2x = 14
x = 7
Using this value, The answers would be the following:
A. 23/21 (assuming you are dividing 2 by 3x; if you multiplied 2/3 by x, the answer would then be 17/3)
B. 21/2
