Answer:
x=0
Step-by-step explanation:
2x^2 -6x -2+x^2+4x
All you have to do is add like terms
2x^2+x^2
= 3x^2
-6x+4x
= -2x
Then add them together to get one equation
3x^2 -2x -2
I recommend you study how to add variables as these are very basic sums. Just practice :)
Let S and B be savings and bills respectively. Then,
S α 1/B
S = k/B Where k = Constant.
When S = $300, B = 65
Then,
300 = k/65
k = 300*65 = 19500
Therefore,
For B = $145,
S= 19500/145 = $134.48
