The correct answer is p/rs.
In order to find this first state the direct variation with the constant k included.
p = krs
Now to find the value of k, we simply divide away the r and s
p/rs = k
Answer:
The word problem is "How many $25 are there in $125?"
<em></em>
Step-by-step explanation:
Given

Required
Write a word problem for the expression
We start by solving the given equation

Divide both sides by $25



This implies that there are 5, $25 in $125
<em>Hence; The word problem is "How many $25 are there in $125?"</em>
Answer:
x = 10 is your answer
- Explain -
Step 1: subtract 1 from both sides (subtraction of equality)
which will give us:
2x = 21 - 1
which equals to
2x = 20
Step 2: Divide both sides by 2
which is
2x/2 = 20/2
2/2 = 1 and 20/2 = 10
Therefore the answer is x = 10
