You can turn 5 into 10/2 and add to x/2
then you need to use simple algebra to left the x alone in the equation so you need to multiply both sides by 2 so you get
2y=10+x
then you need to subtract both sides a 10 so
2y-10=x
now change the x to f'(x) and y to x so:
f'(x)=2x-10
Answer:
13.92
Step-by-step explanation:
You want to divide the cost of the books by the total costs.
308/2800 = 0.11
You then need to convert 0.11 to a percent: 0.11 = 11%
Therefore, 11% of her costs last semester were spent on books.
That’s too much!
