Answer: There are 8 snake and 3 elephants.
Step-by-step explanation:
Let x= Number of snakes
y= Number of elephants
We know that , snake has no legs elephant has 4 legs.
Then, Total animals = x+y=11 (i)
Total legs = 4y = 12
⇒ y=3 .. (ii)[divide both sides by 4]
Substitute value of y from (ii) in (i) , we get
Hence, there are 8 snake and 3 elephants.
First you have to rewrite the equation:
(x ÷ 4) + 8 = 38
Second you have to write the division as fraction:
(¼x) + 8 = 38
Third you have to take off the unecessary bracket:
¼x + 8 = 38
Fourth multiply 8 and 38 by 4
x + 32 = 152
Fifth step move the constant to the right hand and change the sign.
x = 152 - 32
Then subtract:
x = 120

g) c=1.98w is your answer
w = weight = 5.5
c = cost = 10.89
10.89 = 1.98(5.5)
10.89 = 10.89 (true)
hope this helps
