Yes -5/0 is undefined because having 0 of something means you cannot split that 0 into any number so the answer is undefined.
GCF = 50
Just search it on google...
Let's remember that the coefficient in an algebraic expression is always the number that multiplies the variable. Now, in this case we have that the third term is -2x, then:
the coefficient of the third term would be -2
Kayaker=12.5, so 12 knots
Commercials=9 commercials per hour
Dog= 7 miles
Tutoring=750 dollars
I’m not sure if this is what you meant but since you know the surface area of a sphere is 4 Pi r ². You can work backwards and do the opposite (ex: subtraction for addition)
This can help you get the radius as the answer. Since the volume of a sphere is 4/3 Pi r ², just plug in the radius.
