Answer: A quadratic equation is one of the form ax2 + bx + c = 0, where a, b, and c are numbers, and a is not equal to 0. So I think x = 4 but not 100%

Sorry if I'm wrong but I hope this helps

Talia earns 85 cents for cans she recycles.If she gets a nickel for each can,how many cans does she recycle?
Over [174]

Answer:

Step-by-step explanation

Hi there,

We know she gets 1 nickel for every can, and 1 nickel is just 5 cents. So we first get this set up:

\frac{1 \ Nickel}{can} =\frac{5 \ cents}{can}      Now, we also know she gets 85 cents for a certain amount of cans, x:

\frac{85 \ cents}{x \ can}     Now, we can just use the proportionality we designed above, but flip it so <em>cans</em> cancel out:

x \ cans = 85 cents * \frac{1 can}{5 cents} = 17 cans  

Thus, Talia recycles 17 cans.
