Answer (1)
Five times the price of x ballpens → 5xAmount for x kilos of meat at y pesos each → xyAxl got nine more than Gelo’s score (g) → g + 9Each student's share if x marbles are divided by y → x ÷ y or x/yJohn's score: 4 increased by b points → 4 + bAverage of grades m and n → (m + n) ÷ 2Twelve pesos less a discount of d → 12 − dTim’s tokens: x less than 20 → 20 − xTriangle with consecutive sides: a, a+1, a+2 → Perimeter: a + (a + 1) + (a + 2) = 3a + 33 hours less than time traveled t → t − 3
