This is substitution, it's very simple once you get the hang of it!
okay, what you want to do is plug in the numbers you already have, to get the number you don't have(r).
First, you plug in the numbers.
1. P= $2000
A=$2543
t= 4(years)
r=?
2543=2000^r(4)
Secondly, you want to solve the equation.
"the difference of a number x and 4": x - 4
"is": =
"3": 3
Combine the terms so that it looks like the sentence numerically:
"the difference of a number x and 4 is 3": x - 3 = 4
x - 3 = 4 is your answer.
To solve for x:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Add 3 to both sides.
x - 3 = 4
x -3 (-3) = 4 (-3)
x = 4 - 3
x = 1
1 is your answer for x.

Edges that are perpendicular to PR basically means what edges make a 90° angle with PR.
Those edges are HP , RA, TR and QP.
Hence, the answer is A, B and C.
Answer:
45/100 = 0.45
Step-by-step explanation:
Divide 9 by 20.
9/20 = 0.45
Now write 36/100 as a decimal.
36/100 = 0.36
Write 45/100 as a decimal: 0.45
Answer: 45/100 = 0.45
Answer:
I believe that the answer is D.
