Question

2.   Solve the following problem: 17 + 50 – 100 =  (1 point)

–33

33

167

–167



3.   Rewrite the following expression using the Distributive Property. 

5(2x – 8)  (1 point)

–30x

10x – 40

10x + 40

10x – 8



4.   Simplify the following expression: 3(5 – 12) + 4 ÷ 2  (1 point)

–19

19

–23

–8.5

Answer 1

1. -33
2. 10x-40
3. -19

Answer 2

2. -33

3. 10x - 40

4. -19

Explanation:

2. Algebraic addition and subtraction: the negative terms are subtracted from the positive terms

17 + 50 - 100 =

67 - 100 =

- 33

3. The distributive property affirms that the multiplication of a number by a sum is equal to the sum of the multiplications of that number by each of the addends.

5(2x - 8) =

5*2x + 5*(-8) =

10x - 40

4. Priority of arithmetic operators:

(1) Parenthesis

(2) Exponentiation

(3) Multiplication and division

(4) Addition and subtraction

3(5 - 12) + 4 ÷ 2 =

3(-7) + 4 ÷ 2 =

-21 + 4 ÷ 2 =

-21 + 2 =

-19
