Weegy: C. 529 User: Solve this equation: 2s + s + 12 = 132. A. s = –30 B. s = 9 C. s = 40 D. s = 120 Weegy: 2s + s + 12 = 132, 3s + 12 = 132, subtract 12 from both sides, 3s = 120, divide both sides by 3 to get s = 40. Your answer is A. s = 40. User: Simplify this expression: 19 – (–8) – (–14) = ? A. 25 B. –7 C. 41 D. –3 User: Solve the equation: h/9 = 7. A. h = 7/9 B. h = 1 2/7 C. h = 63 D. h = –63 Weegy: h/9 = 7, h=7*9, h=63. The answer is D. h = 63 User: Solve this equation: 80 = 3y + 2y + 4 + 1. A. y = 1/5 B. y = 15 C. y = –15 D. y = 75 User: Solve the following inequality: 38 28 B. x 4 Weegy: The answer to the inequality above is: D. x is greater than 28 User: Solve the inequality: 12p + 7 > 139 A. p > 11 B. p > 12 C. p > 18 D. p > 154 Weegy: 12p + 7>139 12p>139-7 12p>132 p>11 User: Solve the equation: 12y = 132. A. y = 11 B. y = 1/11 C. y = 11/12 D. y = 144 Weegy: c. infinite User: 7. Solve the equation: 12y = 132. User: Solve the equation: 7x = 42. A. x = – 7 B. x = 6 C. x = 7 D. x = – 6 Weegy: 7x = 42 x = 42/7 x = 6 User: Solve this inequality: 3b – 7 Weegy: answer is bUser: Solve this equation for A: A ÷ 2 = 4 A. 8 B. 2 C. 4 D. 6 User: Given the formula K = LMN, what is the formula for M? A. M = K/LN B. M = LN/K C. M = KL/N D. M = LNK Weegy: A. M = K/LN User: Simplify the following expression: 35 + (–13) + (+8) – (–6). A. 36 B. 24 C. 44 D. 50 User: Solve this inequality: 8z + 3 – 2z Weegy: The answer is D. z User: Solve this inequality: 3p – 16 Weegy: pUser: Solve this problem: –282 – (+1,017) = ? A. –1,299 B. 1,299 C. –735 D. 735 Weegy: 282 ? (+1,017) = -282-1017, -282-1017= -1299. Therefore, the answer is A. User: Sue has a balance of $35 in her ... (More)

Weegy: If an object has a mass of 20 kg, the force of gravity acting on it on earth is: W = Force =mg, since the force of gravity on the object is its weight. 20 kg x 9.8 m/s^2 = 196N (More)
