Answer:C- 3x - 7y and 3y - 7x
Step-by-step explanation:
9:7 There are 18 girls to 14 boys. 18/14 divide top and bottom by 2 to simplify equals 9:7
1 yards = 36 inches
3 × 36 = 108
1 foot = 12 inches
108 + 12 =120
So 3 yards and 1 foot is equal
to 120 inches
120 is greater than 100 so 3 yards and 1 foot is greater than 100 inches
The answer is 21 because 21x21x21= 9261
