Question

Sue counted the turtles and birds in the pond. She counted 14 heads and 44 legs.

How many turtles did Sue count?

A.
4

B.
8

C.
11

D.
22\

Answer 1

let x = number of turtles and y = number of birds
then
x + y = 14

turtles have 4 legs and birds have 2
so
4x + 2y = 44

solve these 2 equations for x and y
