The value of QR for the given line will be 15 units.
<h3>What is a line segment?</h3>
A line section that can connect two places is referred to as a segment.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
In other terms, a line segment is merely a section of a larger, straight line that extends indefinitely in both directions.
Given,
PQ = RS
PR = 18
PS = 21
Now,
RS = PS - PR
RS = 21 - 18 = 3
So,
PQ = 3
Now,
QR = PR - PQ
QR = 18 - 3
QR = 15
Hence the value of QR will be 15 units.

The answer to your question is c
Answer:
b = (d-c)/a
Step-by-step explanation:
ab+c=d
Subtract c from each side
ab+c-c=d-c
ab = d-c
Divide by a
ab/a = (d-c)/a
b = (d-c)/a
It is -3 to start off with, on Monday. On Tuesday morning it would be -3 - 2 degrees, = -5 degrees. By Tuesday evening it was 4 degrees lower than in the morning, so -5 - 4 degrees = -9 degrees on Tuesday evening.
Hope this helps xox :)
You'll have to set this up as two separate problems. First, we want to take 15% off the original $20 bill. To do this, you're going to multiply 20 by .15, which gives you $3. So, 15% off $20 is $17.
Now, we want to find 7% of the new bill, so we're going to multiply 17 by .07 to get $1.19, and add it to the $17, making the final bill $18.19. You could also multiply $17 by 1.07 to get your final total without the extra step in the middle, but only do that once you're comfortable with the math.
