Let's focus on the given equation. The C represents the cost, while the x must be the number of tacos, which is what we're solving for. Since we're given the boundary that C must be 300, then the solution would be:
300 = x² - 40x + 610
x² - 40x + 310 = 0
Apply the quadratic formula where a = 1, b = -40 and c = 310. The roots of x are:
x = 29.49≈30
x = 10.51≈11
<em>Thus, she needs to sell either 30 or 11 tacos.</em>
Answer:
z = -1
Step-by-step explanation:
You must first start out by adding 19 to both sides to isolate the variable z, which results in:
2z = -2
Now, you can just divide by two on both sides to get z completely on its own, which gives you:
z = -1
Hope this helped somewhat! :D

Step-by-step explanation:
each page requires 2 Kb.
The USB drive will take 4 * 10^6 Kg
So 4 * 10^6 kb / 2 kb = 2 * 10^6 pages.
Amazing. I don't think this is an exaggeration. It looks just about the way things are.
