Answer:
The correct answer is Option A: Multiplication Property of Equality
Step-by-step explanation:
Given equation is:

The given equation is a linear equation in one variable. Different equality properties are used to solve equations like these.
First of all the denominator with 1/5x has to be eliminated for which the whole equation will be multiplied by 5

This property is called multiplication property of equality.
Hence,
The correct answer is Option A: Multiplication Property of Equality
Answer:
A.) About 90
Step-by-step explanation:
From the given table, the biologist tagged 150 trout. Also, he recaptured a total of 100 trouts of which 60 were recaptured with tags.
Thus, let the trout population in the lake be represented by x,
= 
Cross multiply to have;
100 × x = 60 × 150
100x = 9000
Divide both sides by 100,
x = 
= 90
Therefore, the trout population is about 90 in the lake.
Your total expense would be 35$ because 25+10=35 and then since you are talking about money you add the money sign. Your answer would be 35$
you would have 9.375 pieces or 75/8 pieces, depends on how you look at it
15x+40=115
15x+40-40=115-40
15x=75
15/15 x=75/15
x= 5
