j = 1; one solution 15. 36x = 2(6x + 6x + 36), 6 1.4 Explorations 1. a.A = bh b. 30 = b ⋅ 5; Write the equation. 6 = b; Divide each side by 5. c.A = bh; Write the formula. A — h = b; Divide each side by h. d.applied the same steps to solve; used variables instead of constants 2. a.A = 1 — 2 h (b 1 + b 2); h = 2A — b 1 + b 2; h = 7 cm b ...
1. a. The equation is true if the expression inside the absolute value symbol is 3 or −3; x + 2 = 3; x + 2 = −3 b. x = 1, x = −5 c. Set the expression inside the absolute value symbol equal to both the positive and negative of the constant value, then solve both equations. 2. a. x = −2 b. x = 1 and x = −5; They are the solutions of ...
first of the course, is exploratory in nature and will utilize a basic understanding of rates or ratios. Exercise #1: Answer the following rate/ratio questions using multiplication and division. Show your calculation (and keep track of your units!).
