Answer:
60 chickens
Step-by-step explanation:
We assume the 140 refers to the number animals (heads, noses, bodies, whatever). If all of those were chickens, there would be 280 legs. There are 160 legs more than that.
Since each pig that replaces a chicken adds 2 legs, there must be 160/2 = 80 pigs. That leaves 140 -80 = 60 chickens.
27 time 8 equals 216
...
216 divided by 27 equals 8
Multiply both sides by 2
(2) 18 = x/2 (2)
the /2 (2) gets canceled out
so it's 36= x
Hope this helps
The answer is x=-15 and y=25
The formula for volume is V=LWH
So in this example we have 10.4*5*8
So 8*5=40
40*10.4=416
So the volume is 416 cubic mm
Hope that helped
