The solution(s) of a system of linear equations give points of intersection of specific lines or planes.
The solution(s) of a system of linear inequalities give areas of intersection wherein any specific pair of points or lines are solutions.
PROCESS-WISE there are little differences between solving systems. However, multiplication and division by negatives reverses the signs in inequalities.
Answer:
Margie spent 60% of time in doing science Homework
Step-by-step explanation:
Given:
Time spent in doing maths homework = 25 minutes
Time spent in doing science homework = 60 minutes
Break Time = 15 minutes
To Find:
A percent to represent the portion of time that Margie spent on science homework = ?
Solution:
Let the portion representing the portion of time that Margie spent on science homework be x
The total time spent in doing both maths and science homework and in break time = Time spent in doing maths homework + Time spent in doing science homework + Break Time
The total time spent in doing both maths and science homework and in break time = 25 +60 +15 = 100 minutes
Then
x =
x =
x = 60%
To start off Quantities can be compared in terms of "more", "less", or "equal". (definition)
<em>1. In expressions, there is always a quantity of something, whether an object being weighed, or an object being counted. To show how quantities are related you would have something to equal to, less than, or more than. which is being compared to one another.</em>
2. (12 * x) + 8 //// 8+ 12x //// 8 + (12 * x). This is all based on communitive property, and just switched the numbers around. they all equal to the same answer.
<u><em>3a. 15 + 9x</em></u>
<u><em></em></u>
<u><em>3b. the length would be 9. This is because an equilateral triangle has 3 of the same length of sizes, and x represents the length of each side. making x=3</em></u>

y = -3x + 10
The slope is -3 because the line falls three points for every one over.
the 10 is the y-intercept, as the line crosses the y-axis at positive 10.
