Answer: Calita saw 30 Robins and 6 Cardinals
Explanation:
Step 1
writing the mathemathecal expression becomes
Let robins be represented as R
and Cardinals be represented as C
so our first equation becomes
R+C = 36----- eqn 1
but she saw 5times as many robins as cardinals, with a total of 36 birds making us have
Therefore R= 5C
5C +C= 36------- eqn 2
STEP 2--- solving equation 2
5C+C = 36
6C= 36
C= 36/6=6
Puting the valueof C=6 in equation 1 becomes
R+C= 36
R+6=36
R=36-6= 30
R=30
Therefore Calita saw 30 Robins and 6 Cardinals
