Answer:
8 birds and 6 mice
Step-by-step explanation:
Given:
Number of heads = 14
Number of legs = 40
Required
How many birds and mice are on the ground?
Let M represents Mice and B represents Birds
Birds and Mice have 1 head each;
So;
Birds have 2 legs; Mice have 4 legs
So;
At this point, we have two equations;
Make B the subject of formula in the first equation
becomes
Substitute 14 - M for B in the second equation
Open bracket
Subtract 28 from both sides
Divide both sides by 2
Recall that
So;
<em>Hence, there are 8 birds and 6 mice</em>
Answer:
2/10 & 3/15
Step-by-step explanation:
