Which of the following is a list of equivalent numbers?
2 answers:
Answer:
D
Step-by-step explanation:
We have to find the list of equivalent numbers
A.1.25,,12.5%
12.5%=
Given numbers are not equivalent
Hence, option A is false.
B.0.125,,12.5%
12.5%=
Given numbers are not equivalent.
Hence, option B is false.
C.12.5,,125%
125%=
Given numbers are not equivalent.
Hence, option C is false.
D.1.25,,125%
125%=
Given numbers are equal.
Hence, option D is true.

Set up the following equations:
110 represents the lengths of the length and width of the triangle, as you'll divide total perimeter of the rectangle, 220, by 2 to find the individual lengths. 20 is the difference between the length and width.
We'll use elimination for this system of equations, as there are opposite coefficients for W in both equations. Combine the two equations:
Divide both sides by 2 to get L by itself:
The length of the rectangle is 65 feet.
Plug this value into the second equation:
Add W to both sides:
Subtract 20 from both sides:
The width of the rectangle is 45 feet.
