b = 2A/h

A = ½bh solve for b

π = A/r²

A = πr² Solve for π

Terminating Decimals

a decimal that ends, or terminates

Irrational Numbers

a decimal that never ends and never repeats (No pattern)

Repeating Decimals

a decimal with a digit(s) that repeat in a pattern

Rational Numbers

a number that can be written as a fraction, terminating or repeating decimals

y = (x + 4)/x

x = xy -4 solve for y

x = 6

2x + 7 = x + 3 + 10

x = 3/2y + 3

2x - 3y = 6 solve for x

y = 2/3 x - 2

2x - 3y = 6 solve for y

x = 12

3(x - 1) = 2x + 9

x = 2/3y + 2

3x - 2y = 6 Solve for x

y = 3/2x - 3

3x - 2y = 6 solve for y

Rational

-67.98

x = 7/2 - y

7 = 2(x + y) solve for x

Natural

8

x = 0

8(x + 2) = 2x + 16

Integer

-8, 0, -5, 5,

Whole Numbers

0,3, 4, 6, 10

Rational

-1.97

Rational

2.44444....

Rational

1/3

x = 5

10+5x=7x

Integer

100, -68, 2, -56,

x = -6

12 - 5 - (3 + x) = -2 - 2x

x = -3

4x + 2x + 2 = 3x - 7

x = -4

4x + 2x - 5 = 7x - 1

x = 10

4x - 6 = -7x + 4 + 10x

x = 3

5x-16=14-5x

r = C/2π

C = 2πr solve for r

Integers

whole numbers and their opposites (negatives)

x = ½y + 8

y = 2(x - 8) solve for x

x = -1

−18 − 6x = 6 (1 + 3x)
