4
Step-by-step explanation:
1 + 1 + 1 + 1 = 4
2 + 1 + 1 = 4
3 + 1 = 4
4 = 4

Let the number of chickens = c.
Let the number of pigs = p.
A chicken has 1 head and 2 legs.
c number of chickens have c heads and 2c legs.
A pig has 1 head and 4 legs.
p number of pigs have p heads and 4p legs.
There are 40 heads.
Equation for heads:
c + p = 40
There are 110 legs.
Equation for legs:
2c + 4p = 110
System of equations:
c + p = 40
2c + 4p = 110
Solve the first equation of the system of equations for c:
c = 40 - p
Substitute 40 - p for c in the second equation:
2c + 4p = 110
2(40 - p) + 4p = 110
80 - 2p + 4p = 110
80 + 2p = 110
2p = 30
p = 15
Now substitute p = 15 in the first equation to find c.
c + p = 40
c + 15 = 40
c = 25
There are 25 chickens and 15 pigs.
Hmm, Its pretty blurry and nice cat but I will try for ya :D ***cant gurantee its gonna be correct***
6 3/4 =27/4
2/3= 0.666666666 (0.66)
1 3/4= 7/4
2 1/4 = 9/4
(i can't solve this im so sorry holy shoot)
Answer:
<em>I think it didnt change</em>
Step-by-step explanation:
<em>Cause both areas from the line are the same and if it were to change the left would be diffrent from the right. So there i think it didnt change.</em>
4n-40=7(-2n+2)
4n-40=-14n+14
subtract -4n from both sides
-40 = -18n +14
subtract -14 from both sides
-54=-18n
divide both sides by -18
3 = n
