X= -3
2/3x-10=12
Step 1: Add 10 to both sides.
2/3x=-2
Step 2: Multiply both sides by 3/2.
x= -3
When an equation is in standard form, x isn't negative so she should divide everything by a negative 1 to change it into a positive equation.
I think it is B I hope I am right and helped
Equality between the values, equations, or expressions written on both sides.
Answer:
Adult tickets sold= 9x4 = 36
Senior tickets sold = 9x3= 27
Child tickets sold = 9 x 1 = 9
Step-by-step explanation:
If the parts for adult tickets changed within the 2 ratios given, we should have equated Ratio further. But here that is not 5e case. So, put both ratios together:
Senior:Adult:Child
3:4:1
Now,
Total number of parts 3+4+1=8
Number of tickets sold per part = 72/8 = 9
Therefore number of
Adult tickets sold= 9x4 = 36
Senior tickets sold = 9x3= 27
Child tickets sold = 9 x 1 = 9
Hope this helps.
Good Luck
