Answer : 11 3/5 inches each or 11.6 inches each
Step-by-step explanation:
There are 3+1 foot=4ft each foot is 12 inches4x12=48+10=58
So you have 58 inches of ribbon. 58/5 =11 3/5 inches each or 11.6 inches each
Let h = the number of horses in the field
Let c = number of cows in the field
There are 2 more horses than cows in the field. Therefore
h = c + 2
or
c = h - 2 (1)
There are 15 animals in the field. Therefore
h + c = 15 (2)
Substitute (1) into (2).
h + (h - 2) = 15
2h - 2 = 15
Answer:
The correct equation is
2h - 2 = 15
