A is like toats larger but feel to bored to explain it
A becaus eit does not give fraction always change to fractions</span></span>
Approximately equal to symbol
And it’s mostly used in terms of numerical approximations
You can do
70 x 6000
and
6000 x 70
=420000
Answer:
let the number of cows = x
let the number of chickens = y
since there are 42 heads:
x + y = 42
and since a cow has 4 legs, and a chicken has 2
4x + 2y = 144
from first equation:
x + y = 42
x = 42 - y (now, we will substitute this in the second equation)
4(42 - y) + 2y = 144
168 - 4y + 2y = 144
2y = 168 - 144
2y = 24
y = 12
now, we know the number of chickens. we will replace y with 12 in the first equation since it is more simpler
x + 12 = 42
x = 30
So, there are 30 cows and 12 chickens
