Answer:
If we assume that everyone in the group is an owner, we would have
legs.
legs
Therefore, we need 24 more legs.
These 24 additional legs can be made from the difference of legs between the owners and dogs.
In this case, dogs have more legs than an owner.
24 ÷ 2 = 12.
There are 12 dogs in the group.

Answer:
option Bis correct answer.
Step-by-step explanation:
given, a line passes through the point (_1,3)and has slope 2.let another point be x2 and y2.
by the slope formula,
slope (m)=
or , 2=y2_3/x2_(_1)
or, equating with slope we get,
2=y2_3
or, y2=5
again, 2=x2+1
therefore, x2=1
so the points are (1,5)........ans....
