You would want to subtract 18 from 45. Your answer would be y=27.
I believe the answer is 2, because if you divide 2.0 by 1 you get 2 and if you divide each row you get 2
In this equation you have 3m+3=15 or 3m+3=-15. Solving for m on both you get m=4 or m=-6. The answer is D.
The answer of this question is b
I'm pretty sure the answer is B) 11c+8.5(c-46)=470
hope i help :)
