Express 0.456 as a percent. A).00456% B)4.56% C)45.6% D)456%

Using Percents Interest = chief × rate × time Mr. Sam obtained $1000 for 6 months at a yearly financing cost of 27 percent. What amount of intrigue did he pay?

Exponents Multiply terms with examples by including types Divide terms with types by subtracting types

Exponents Simplify: p - 2 p 5 A)p - 10 B)p - 3 C)p 3 D)p 7

Scientific Notation Huge Numbers Tiny Numbers

Estimates You have a mini-computer – utilize it ! Fundamental thought Round the numbers in the issue so you can figure it out in your mind… (or on your fingers) 12,357 gets to be 12,000 3.12 gets to be 3

Properties of Numbers Remember the Names Commutative "drive" 3 + 5 = 5 + 3 Associative " relate at a gathering in various gatherings" 4(2x + 3) = (2x + 3)4 Distributive 3(5 + 1) = 3 × 5 + 3 × 1 Identity "reflect #" (Addition ) -3 + 0 = - 3 Identity "reflect #" ( Multiplication) 5 × 1 = 5

Rules for Integers Use the mini-computer!!! Including 2 positives = positive 2 negatives = negative Subtracting Subtraction is simply including the inverse sign 3 – - 5 = 3 + - (- 5) = 3 + 5 = 8 Multiplying and Dividing 2 positives or 2 negative = positive 1 positive and 1 negative = negative

Order of Operations P Parenthesis E Exponents M, D Multiply & partition A, S Add & subtract

Simplify: 2 3 + 4 - 6 2 A) - 26 B) - 22 C) - 2 D) 10

Evaluate Algebraic Expressions Evaluate a mathematical expression intends to substitute a number for every variable and afterward do the demonstrated operations – recollect to take after the request of operations .

If r = - 6, s = - 2, t = - 3 v = 10, and w = - 1/2 then wv|-t - s| = A) - 25 B) - 5 C) 5 D) 25

Write Algebraic Expressions Translate word for word into arithmetical images The total of an and b increased by 66% A number partitioned by two is equivalent to 66% of another number

Which speaks to the sentence twenty not as much as triple a number is thirty ? 20 – 3x = 30 20 – 3x > 30 3x - 20 < 30 3x – 20 = 30

Solve Equations Keep it adjusted Perform the inverse operations

Solve the condition for x. - 16 - 32/3 32/3

Solve for x Solve the quadratic condition: 4x 2 - 9 = 0 A) 3/2 B) - 3/2 C) 9/4 and - 9/4 D) 3/2and - 3/2 If you\'re confused, simply utilize your number cruncher to connect to all responses for x! Keep in mind x 2 conditions have TWO arrangements!

Linear Equations-capture strategy y block ( x = 0) x catch ( y = 0)

Linear Equations – Slope positive indistinct negative zero

- 3 0 Solve and Graph Inequalities Same as conditions EXCEPT when increase or separation by a a negative number flip the imbalance

6x - 2(x + 1) > 0 Solve the disparity. A) x > 2 B) x < 2 C) x < 1/2 D) x > 1/2

Solve. Understand the disparity. - 2 x + 5 ≥ 3 x + 20 A) x ≤ 3 B) x ≥ 3 C) x ≤ - 3 D) x ≥ - 3

Systems of Linear Equations Solution Main Idea The answer for an arrangement of conditions is the point where the 2 lines meet When you substitute the arrangement, it must make BOTH conditions genuine !!

Identify the answer for the arrangement of conditions diagramed. (0, 1) (1 - 1) (0, - 3) (- 1, 1)

Systems of Equations – Substitution substitute

x = y - 3 x + 3y = 13 What is the answer for the arrangement of conditions? A) (1, 4) B) (4, 1) C) (2.5, 5.5) D) (5.5, 2.5)

Systems of Equations – Elimination dispose of y include both conditions

2x - 3y = 16 5x - 3y = 13 What is the answer for the arrangement of conditions? A) (- 1, - 6) B) (- 6, - 1) C) (5, - 2) D) (5, 4)
