Which of the following is not a part of PEMDAS, the acronym for math order of operations?

88% Answer Correctly

	addition
	exponents
	pairs
	division

Solution

When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)

A right angle measures:

90% Answer Correctly

	180°
	90°
	360°
	45°

Solution

A right angle measures 90 degrees and is the intersection of two perpendicular lines. In diagrams, a right angle is indicated by a small box completing a square with the perpendicular lines.

Solve for b:
-3b + 1 = 9 + b

59% Answer Correctly

	-1\(\frac{3}{4}\)
	8
	-1\(\frac{4}{5}\)
	-2

Solution

To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.

-3b + 1 = 9 + b
-3b = 9 + b - 1
-3b - b = 9 - 1
-4b = 8
b = \( \frac{8}{-4} \)
b = -2

If BD = 23 and AD = 27, AB = ?

76% Answer Correctly

	8
	10
	6
	4

Solution

The entire length of this line is represented by AD which is AB + BD:

AD = AB + BD

Solving for AB:

AB = AD - BD
AB = 27 - 23
AB = 4

70% Answer Correctly

	equal angle
	parallel
	right angle
	equal length

Solution

A trapezoid is a quadrilateral with one set of parallel sides.
