So burger king offers 10 chicken nuggets for $1.49
1 chicken nugget = price for 10 chicken nugget / 10 chicken nugget
= $1.49 / 10 = $0.15 per nugget (approximated)
Hope that helps!
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
A² + b² = c²
5² + 8² = x²
x² = 25 + 64
x² = 89
x = √89
x = 9.43
