Solve the following equation: 2x + 4 = 16 x = 10 x = 6 x = 2 none of these first subtract 4 from both sides of the equation then multiply by 1/5 on both sides of the equation Which one shows the steps for solving this equation? 1/5x + 4 = -2 first subtract 4 from both sides of the equation then divide by 1/5 (or multiply by its reciprocal 5/1) on both sides of the equation. first divide by 5 on both sides of the equation then subtract 4 from both sides of the equation first add 10 to both sides then multiply by -7 onboth sides; solution is -196 Which one describes how to solve this equation? -7x -10 = 18 first add 10 to both sides of the equation, then divide by -7 on both sides; solution is -4 first add -10 to both sides then divide by -7 on both sides; solution is 8/7 Paul joins a gym. The gym cost $20 a month plus a membership fee of $50. If Paul paid $270, how many months has he been a member of the gym? 20(m + 50) = 270; 8 months m(20 + 50) = 270; almost 4 months 20m + 50 = 270;11 months John wants to have a paintball party. The arena cost $100 to rent and then there is a $20 charge per person. Write and solve an equation to show how many people attended if John’s party cost $300. 120p = 300; 2.5 people 100 + 20p = 300; 10 people 100p + 20 = 300; 3 people The carnival has a $5 entrance fee and then charges $1.50 per ride. If Sue went to the carnival and spent $44.00, write and solve an equation to show how many rides Sue rode. 1.50r + 5 = 44; 26 rides 5(1.50) + r = 44; about 36 rides 5r + 1.50 = 44; 8.5 rides |
