Solve as you would an equation, except when you divide by −2, you need to flip the inequality symbol. 0.1 − 2t ≥ 0.7 −2t ≥ 0.6 t ≤ −0.3 {Ans: Solve for t. 0.1 − 2t ≥ 0.7 A. t ≥ −0.4 B. t ≤ −0.4 C. t ≤ −0.3 D. t ≥ −0.3}To convert the percent to a decimal, divide by 100 and drop the percent sign. Then, "of" is a keyword meaning to multiply. 0.0015(6,000) = 9 6,000 − 9 = 5991 gears {Ans: The failure rate of gears from a factory is 0.15%. Out of 6000 gears produced on Tuesday, how many are expected to function properly? A. 3000 gears B. 5100 gears C. 5910 gears D. 5991 gears}Start by writing 5y/2 as 2.5y. Next, subtract 1.5 from both sides of the inequality: 6.5 - 1.5 > 1.5 + 2.5y - 1.5 5 > 2.5y When each side of the inequality is divided by 2.5, the result is 2 > y, which is the same as y < 2. {Ans: Solve the inequality for y. A. y > 1.6 B. y < −2.5 C. y < 2 D. y > 2}The easiest method
