Answer:
l don't know ;) but l can't help but
Given: PQ=2x-3. if QR=5x+7 and PR=10x-11
To Find: PR
Solution: From the attached diagram, point P, Q and R are co-linear.
Hence, PR = PQ + QR
or, 10x-11 = 2x-3 + 5x+7
or, 10x - 7x = 15
or, x = 5
Now, we shall calculate the value of PR
PR = 10x-11
or, PR = 10× 5 - 11
or, PR = 39
Hence, the required value of PR will be 39.
this is just a question I'm sorry but what grade is this for?
Answer:
They should sell 20 band posters.
Step-by-step explanation:
24 is 1/5 of 120 so we must find what 1/5 of 100 is.
it is 20.
The correct answer is this one: "<span>C) 52 in3."

Given the illustration, we can be able to know the dimensions of the formed box.
The dimensions are
Length: 10 - 2x
Width: 8 - 2x
Height: x
So the volume is
Volume = (10-2x) * (8-2x) * (x)
Let x = 2.5
Volume = (5) * (3) * (2.5) = 37.5
Let x = 2
Volume = (6) * (4) * (2) = 48
Let x = 1.5
Volume = (7) * (5) * (1.5) = 52.5
Let x = 1
<span>Volume = (8) * (6) * (1) = 48
</span>Let x = 0.5
<span>Volume = (9) * (7) * (.5) = 31.5
