Front

An equation involving two or more variables

Back

Dimensional Analysis

Front

changing from one unit to another via conversion factors aka unit analysis

Back

Scale

Front

Specify a percentage of original size to enlarge or reduce the size of an object.

Back

Rate

Front

A ratio that compares two quantities measured in different units a price of $9.99 for 10 songs is a rate

Back

Addition Property of Equality

Front

if you add the same number to each side of an equation, the two sides remain equal For any real number a, b, and c, if a = b, then a + c = b + c.

Back

Solve an Equation

Front

to find the value of the variable that makes the equation true

Back

Multi-step Equations

Front

Equations that need more than one step to solve 3x-7=2

Back

Multiplication Property of Equality

Front

Multiplying the same number to each side of the equation produce an equivalent equation For any real number a, b, and c, if a=b, then ca=cb

Back

Equivalent Equations

Front

equations that have the same solution

Back

Proportion

Front

An equation stating that two ratios are equal

Back

Formula

Front

a rule for the relationship between certain quantities.

Back

Scale Model

Front

A model of an object in which the dimensions are in proportion to the actual dimensions of the object.

Front

an equation that is true for all values; infinity many solutions 3(2b-1)-7=6b-10

Back

Subtraction Property of Equality

Front

if you subtract the same number from each side of an equation, the two sides remain equal For any real number a, b, and c, if a = b, then a - c = b - c

Back

Consecutive Integers

Front

integers in counting order, such as 4, 5, 6 or n, n+1, and n+2.

Back

Percent of Change

Front

The ratio of the amount of change to the original amount expressed as a percent

Back

Percent of Increase

Front

the percent of change when the new amount is greater than the original

Back

Percent of Decrease

Front

Percent of change where the new number is less than the original number

Back

Means

Front

in a proportion they are the middle terms in a/b=c/d b and c are means

Back

Division Property of Equality

Front

Dividing the same number to each side of the equation produce an equivalent equation For any real number a, b, and c, If a=b and c≠0 then a/c = b/c.
