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}Write each mixed number as an improper fraction. Then, get a common denominator (which is 10). 11/2 + 39/10 = 55/10 + 39/10 = 55 + 39/10 = 9 4/10 = 9 2/5 {Ans: 5 1/2 + 3 9/10 = A. 8 1/5 B. 9 2/5 C. 8 2/5 D. 9 1/5 E. None of these}The formula for the area of a trapezoid is: A = 1/2h (b1+b2) Substitute given values into the formula and solve for the unknown base: 864 = 1/2 ⋅ 24 (30+b2) 864 = 12 (30+b2) 864 = 360 + 12b2 504 = 12b2 42 = b2 The length of the base is 42 cm. {Ans: The area of a trapezoid is 864 cm^2. It has a height of 24 cm, and the length of one of its bases is 30 cm. What is the length of the other
