So the formula for that is:
(total - difference) ÷ 2 = smaller number
(total + difference) ÷ 2= larger number
In this case, Judy is more so we do second fomula:
(12 + 6) ÷ 2 = 9 hits homerun
and Marnie will hit 12 - 9 = 3 hits
For option d:
5x - 7y = 10 . . . . . (1)
10x - 14y = 8 . . . . (2)
(1) x 2 => 10x - 14y = 20 . . . . . (3)
(2) - (3) => 0 = -14 [not possible]
Therefore, the set of equations in option d, has no solutions.
Answer: .15% (point fifteen percent)

Step-by-step explanation:
The answer would be because you will be adding them anyway when multiplying
