Answer:
It’s 2+2=x 3x3=18 that’s the answer
Step-by-step explanation:
30:50 = 3:5
x : x+25 = 3:5
25/2 x 3 = 37.5
The starting equation is
12-(3x+13)=0
First add 3x+13 to both sides so that only 12 is on the left
12=3x+13
now subtract 13 from both sides to isolate your variable
-1=3x
Finally divide both sides by 3 to get your final answer
x=-1/3
answer c. none of the above
