1.1 Expressions & Formulas
Evaluate each expression if x = -‐3 and y = -‐4 1. 7𝑥! − (𝑥 + 𝑦)! 2. 𝑦 − 2𝑥 3. – (𝑥 − 3𝑦)! 1.2 Properties of Real Numbers Simplify each expression. 4. − !
!21𝑥 − 7 + 2(4 − 6𝑥) 5. – 3𝑔 + 3𝑏 − 5(𝑔 − 2𝑏)
Name the sets of numbers to which each number belongs . (Natural, Whole, Integer, Irrational, Rational, Real) 6. 0.125 7. !
! 8. 2 9. 0
Name the property illustrated.
10. 𝑎 + 0 = 𝑎 11. !!∗ !!= 1 12. 𝑎 + 𝑏 + 𝑐 = 𝑏 + 𝑐 + 𝑎
13. 𝑎 + 𝑏 + 𝑐 = 𝑎 + 𝑏 + 𝑐 14. 1 ∗ 9 = 9 1.3 Solving Equations Solve each equation for the given variable.
15. 5 2 − 3𝑥 = 7𝑥 + 4 16. 3 = !(!!!)!
Define your variable, write the equation and solve the problem. 17. The length of a rectangle is 5 more than twice its width. Find the length of the rectangle if the perimeter is 100 centimeters. 18. The formula for Area of a triangle is: 𝐴 = 𝑏ℎ
2 If the Area of the triangle is 12 sq. in. and the height is 3 in., what is the base? 19. Bill purchased chips for the student council meeting. He paid $2.98 for each bag of Central Market organic chips and $1.98 for each bag of HEB’s brand. He purchased 3 more bags of HEB brand than Central Mkt.. His total bill was $15.86. How many of each did he buy? 1.4 Solving Absolute Value Equations Solve each equation.
