Answer:
40 hens, 5 sheep
Step-by-step explanation:
40 x 2 = 80 (hens have 2 legs)
100 - 80 = 20 ----> 20 legs left for sheep,, sheep have 4 legs
20/4 = 5 so there are 5 sheep
Y=140 because U have to go 35 divided by 2 and 8 times 17.5
Word Form: Seven hundred ten thousand two hundred.
2.80 is more than 2, i would round it.
So sorry if this is wrong :(
It is 18 because it is a square so all the sides have to be the same so that would make it 18
