A number divided by six is twenty-one

126

Step-by-step explanation:

if you divide 126 by 6 you get 21

the way you get 126 is you times 6 by 21 (reverse operation) to get that unknown number which is 126 in this case

126

Step-by-step explanation:

To find the answer to this, you need to do the inverse (opposite) of times, which is divide.

the answer is c)8

step-by-step explanaction:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
