Question

By the end of the first quarter of a football game, Gary had gained 42 yards and lost 9 yards. Gary lost an additional 18 yards and gained 58 yards in the second quarter. Write an equation to represent his total yardage for the first half of the game.

Answer 1

42 - 9 - 18 + 58 = y

Step-by-step explanation:

Gary's total yardage for the first half of the game can be represented by the equation 42 - 9 - 18 + 58 = y, where y is the number of yards Gary had at the end of the first half. In this equation, the first term (42) represents the number of yards Gary gained in the first quarter, the second term (-9) represents the number of yards he lost in the first quarter, the third term (-18) represents the number of yards he lost in the second quarter, and the fourth term (58) represents the number of yards he gained in the second quarter. When we combine these terms, we get the total number of yards Gary had at the end of the first half of the game.

For example, if we plug in numbers for the yardage gained and lost in each quarter, we can solve the equation to find Gary's total yardage for the first half of the game:

42 - 9 - 18 + 58 = y

15 + 58 = y

73 = y

Therefore, Gary had 73 yards at the end of the first half of the game.
