A football team lost 5 yards and then gained 9. What is the team's progress?
For lost, use negative. For gain, use positive. Progress = -5 + 9 = 4 yards
Mary, Peter, and Lucy were picking chestnuts. Mary picked twice as much chestnuts than Peter. Lucy picked 2 kg more than Peter. Together the three of them picked 26 kg of chestnuts. How many kilograms did each of them pick?
Let x be the amount Peter picked. Mary picked twice as much chestnuts than Peter - 2x Lucy picked 2 kg more than Peter - x + 2 Total chestnut is 26. Equation: x + 2x+ x + 2 = 26 Solve for x. Simplify the equation by adding the common terms. x + 2x+ x + 2 = 26 4x + 2 = 26 4x = 26 - 2 (transpose +2 to the other side *sign will be changed) 4x = 24 (simplify and divide both sides by 4) x = 6 Substiture x. Peter's expression is x. x = 6 Mary's expression is 2x = 2(6) = 12 Lucy's expression is x + 2 = 6 + 2 = 8 Therefore, Peter, Mary, and Lucy picked 6, 12, and 8 kg, respectively.
