Algebra
The inverse of -9n is dividing by -9.
Wouldnt that be 2+5 ?? if x is 2 it’s simple, just add them and you get 7.
Is there a picture that I’m able to look at??
Answer:
D
Step-by-step explanation:
We can test each pair making each ratio into its simplest form.
For A 2/3 is already in its simplest form and 9/15=3/5. they are not equivalent.
For B, 5/8 is already in its simplest form and 15/21=5/7. they are not equivalent.
For C, 3/12=1/4, and 6/18=1/3. They are not equivalent.
For D, 4/10=2/5, and 12/30=2/5. They are equivalent.
