Shirts and pants are both $2 each.
Using the elimination method, we can solve this system of equations. You must find a common multiple of both equation for either x or y. I chose to multiply equation 2 by (-2) so that the x would be eliminated, allowing us to solve for y.

The vocabulary terms have been matched to the correct definitions as follows;
- Direct variation: describes variation between proportional relationships
- Slope: a ratio describing vertical change to horizontal change of a linear relationship on a coordinate grid
- Rate of change: a number, k, that represents the unit rate used in a direct variation equation y = kx for comparing proportional relationships between two variables x and y found by using division
- Unit rate: a speed or rate of change where the denominator (or second quantity measured) in the ratio is 1
- Constant of proportionality: the ratio of vertical change to horizontal change rate of change
<h3>What are Mathematical Terms?</h3>
- Mathematical terms refer to phrases and words that define certain arithmetic standards.
- The above are the definitions of the mathematical terms. Direct variation, for instance, expresses the relationship between two variables, x, and y.
- The slope is often used after graphing and indicates the relationship of change between the vertical and horizontal axes.

Just like regular numbers, angles can be added to obtain a sum, perhaps for the purpose of determining the measure of an unknown angle. Sometimes we can determine a missing angle because we know that the sum must be a certain value. Remember -- the sum of the degree measures of angles in any triangle equals 180 degrees. Below is a picture of triangle ABC, where angle A = 60 degrees, angle B = 50 degrees and angle C = 70 degrees.
The angles of this triangle are 50, 60, and 70 degrees.
Because you can’t multiply 5x10 to get 1
