Answer to Problem 3GP
The equation is
Explanation of Solution
Given:
Concept Used:
- To get rid of a number in addition from one side, subtract the same number from both sides of equal sign.
- To get rid of a number in subtraction from one side, add the same number both sides of equal sign.
- To get rid of a number in multiplication from one side, divide the same number from both sides of equal sign.
- To get rid of a number in division from one side, multiply the same number both sides of equal sign.
Rules of Addition/ Subtraction:
- Two numbers with similar sign always get added and the resulting number will carry the similar sign.
- Two numbers with opposite signs always get subtracted and the resulting number will carry the sign of larger number.
Calculation:
In order to find the number of ounces in any number of pounds. Let we asume that pounds is denoted by y and ounce is denoted by x
Thus, the equation is
(b)
The number of ounces in

Answer to Problem 3GP
The table is below:
x | y |
5 | 80 |
8 | 128 |
11 | 176 |
13 | 208 |
Explanation of Solution
Given:
Calculation:
In order to find the number of ounces in
Thus, the table for r is below:
x | y |
5 | 80 |
8 | 128 |
11 | 176 |
13 | 208 |
(c)
The graph for the realtion.
(c)
Answer to Problem 3GP
Explanation of Solution
Given:
The pair of points are
Concept Used:
The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis.
Then, algebraically,
- an x-intercept is a point on the graph where y is zero, and
- a y-intercept is a point on the graph where x is zero.
More specifically,
- an x-intercept is a point in the equation where the y-value is zero, and
- a y-intercept is a point in the equation where the x-value is zero.
Calculation:
In order to plot the points in graph we take all points from the table. The points are
