kris kringle has alot of reindeer and snowbirds but no other pet. among his pet kris counted 42 heads and 134 legs. how many rei
vlada-n [284]

Answer:

There are 25 reindeers and 17 snowbirds

Step-by-step explanation:

A reindeer has 4 legs while a snowbird has two legs

Let the number of reindeer be x while the number of snowbirds is y

Total heads is 42;

x + y = 42 •••••••(i)

let’s now count the legs

4(x) + 2(y) = 134

4x + 2y = 134 ••••••(ii)

divide ii by 2

2x + y = 67

y = 67 - 2x

and from i above too, y = 42-x

equate the y

67-2x = 42-x

67-42 = -x + 2x

x = 25

y = 42-x

y = 42-25

y = 17
