(a)
Answer to Problem 13MCQ
An equation to find the length of the average common goldfish is
Explanation of Solution
Given information:
The average length of a yellow banded angelfish is 12 inches.
The length is 4.8 times as long as average length of common goldfish.
Concept used:
Algebraically conversion of verbal statement.
Calculation:
Consider the statement.
The length is 4.8 times as long as average length of common goldfish.
Let us consider that average length of common goldfish is
So, 4.8 times of
This is equal to 12 inches.
So, the required equation for length will be
(b)
To find: the length of the average common goldfish.
(b)
Answer to Problem 13MCQ
The length of the average common goldfish is
Explanation of Solution
Given information:
The average length of a yellow banded angelfish is 12 inches.
The length is 4.8 times as long as average length of common goldfish.
Calculation:
Consider the equation from part (a).
Now, solve the equation for
Hence, the length of the average common goldfish is
(c)
To find: the mathematical practice to solve the problem.

Remember that: A matrix is in row echelon form if Any row that consists only of zeros is at the bottom of the matrix. The first non-zero entry in each other row is 1. This entry is called aleading 1. The leading 1 of each row, after the first row, lies to the right of the leading 1 of the previous row.arrow_forward
