Answer:x=12
Step-by-step explanation:
5x+9-3x=18+15
First of all, in the case of a equation that has one vatiable having one power ,you need to bring all the variable together in one side.
5x-3x=18+15-9
0r,2x=18+6
Or,2x=24
Or,x=24/2
Or,x=12
So it's the solution..
You would simply do 33.3/370, which results in 0.09. Converting that to a percentage you get that the sales tax is 9%.

Answer:
1/2
Step-by-step explanation:
quadratic equation is ax²+bx+c=0
Products of roots is c/a
Sum of roots is -b/a
On comparing the above equation with general equation we have
a=1
b=-(3k)
c=-(k+2)
Now it is given that sum of roots and product of roots is equal
So,
-b/a=c/a
-b=c
-[-(3k)]=-(k+2)
3k=-k-2
3k+k=-2
4k=-2
k=-1/2

Answer: $10.45 (choice C)</h3>
Work Shown:
20% = 20/100 = 0.20
20% of 52.25 = 0.20*52.25 = 10.45
side note: The total cost, including the tip, is 52.25+10.45 = 62.70 dollars
