Question

Can someone please help me on this?? ill mark branliest for the best answer

Answer 1

12 -1/9d = 17

Subtract 12 from both sides

-1/9d = 5

Multiply both sides by -9:

D = -45

The answer is b. d = -45

Answer 2

Answer:

d = -45

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    12-1/9*d-(17)=0

Simplify 1/9

2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  9  as the denominator

 Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible

Rewrite the whole as a fraction using  9  as the denominator

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Now, on the left hand side, the  9  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

Add  45  to both sides of the equation :

                     -d = 45

Multiply both sides of the equation by (-1) :  d = -45

Hope this helps1
