a) The number of students who enjoy reading only.
Using the multiplication property, we have the following equivalent system of linear equations:
- 4/9x + 4/3y = 20/12
- 2/3x - 4/3y = 5/3
<h3>What is an Equivalent System of Linear Equations?</h3>
- Systems that are equivalent will have the same solution.
- Creating equivalent system helps us to find the variables in a system of equations.
Given:
1/3x + y = 5/4 ---> Equation 1
2/3x - 4/3y = 5/3 ---> Equation 2
To create an equivalent system, multiply equation 1 by 4/3, and multiply equation 2 by 1.
Thus, using the multiplication property, we have the following equivalent system of linear equations:
- 4/9x + 4/3y = 20/12
- 2/3x - 4/3y = 5/3

Answer:
8 loads can be expected to occur during a 4-year period
Step-by-step explanation:
This question can be solved by a simple rule of three.
Suppose the mean time between occurrences of loads is 0.5 year.
This means that for 0.5 years, 1 occurence is expected.
(a) How many loads can be expected to occur during a 4-year period
0.5 years - 1 occurence
4 years - x occurrences
8 loads can be expected to occur during a 4-year period
Answer:
Total number of tile used = 300
Step-by-step explanation:
Given:
Length of floor = 240 inches = 240 / 12 = 20 ft
Width of floor = 180 inches = 180 / 12 = 15 ft
Size of each tile = 1 square foot
Find:
Total number of tile used
Computation:
Area of floor = 20 x 15
Area of floor = 300 square foot
Total number of tile used = Area of floor / Size of each tile
Total number of tile used = 300 / 1
Total number of tile used = 300
