Answer: First option
12 candy bars were sold
Step-by-step explanation:
Call x the amount of candy sold and call z the amount of cookies sold. Then we know that

We also know that candy bars sell for $ 3 and cookies sell for $ 5. The profit was $ 76
So:

To find the quantity of candy bars sold we must solve the system of equations:

Multiply the first equation by -5 and add it to the second equation

+

The total length of the tree will be given by:
Total=(elevation above the ground)+(length of the root)
elevation=28 ft
length of the root=13
thus the length of the tree will be:
28+13
=41 ft
The width is 3m because 3*7 is 21m^2. Also they said the length is 4 more than the width (3+4=7)
The probability would be 1/2
Answer:

Step-by-step explanation:
The general equation of a line: 
In our case <em>a</em> is given

Now we plug in for <em>a</em> and we get:

Now we plug in our coordinates into this equation and we solve for <em>b</em>

So the equation of the line is
