Front

What is the formula for the perimeter of a triangle?

Back

The perimeter of a triangle is the sum of the lengths of its three sides: P = a + b + c.

Front

If one side of a triangle is represented as 3x, what does this mean?

Back

It means that the length of that side is three times the value of x.

Front

How do you solve for x in the equation 3x + (-3x + 12.5) + (2x - 4.25) = 43.5?

Back

Combine like terms and isolate x: 3x - 3x + 2x + 12.5 - 4.25 = 43.5.

Front

What is the first step in solving the inequality 18 < 4m - 15?

Back

Add 15 to both sides to isolate the term with m: 18 + 15 < 4m.

Front

What does it mean for a number to be a solution to an inequality?

Back

A number is a solution to an inequality if it makes the inequality true when substituted into it.

Front

How do you convert a mixed number to an improper fraction?

Back

Multiply the whole number by the denominator, add the numerator, and place that over the original denominator.

Front

How do you add fractions with different denominators?
