Answer:
1: 42
2: 107.6 °F
Explanation:
For question 1 you insert the x and y values into the expression:
8 × 5 = 40 (xy = 40)
40 - 8 = 32 (xy - x = 32)
2 × 5 = 10 (2y = 10)
32 + 10 = 42 (xy - x + 2y = 42)
For question two you insert the celsius value into the expression:
9/5 × 42 = 75.6 (9/5C = 75.6)
75.6 + 32 = 107.6 (9/5C + 32 = 107.6)
