Answer:

A example: A customer brought 5 quarts of lemonade from Leah's stand. She also tipped Leah an additional $2. The customer finally paid a total of $27 including the tip. How much is each quart of lemonade worth? If x is what the lemonade is worth, write an equation to figure out the total.

In this problem, the x is what the lemonade is worth. So you should start with a 5x. The customer also tipped $2. So you should add 2 to the 5x. We also know the total, 27.

With the information we can form an equation.

5x + 2 = 27.

To solve, we can subtract 2 from both sides and finally dived by 5 on both sides as well. Your final answer should be x = 5.

Hopefully this is what you're looking for, sorry for being late!

How to solve this equation equal to zero

3x² -16x-12 =0

We can solve this equation using formula.

a=3, b=-16, c=-12

$x= \frac{-b+/- \sqrt{b^{2} -4ac} }{2a} 
\\ \\ x= \frac{16+/- \sqrt{16^{2}+4*3*12} }{2*3} = \frac{16+/- \sqrt{400} }{6} = \frac{16+/-20}{6} 
\\ \\ x_{1}= \frac{16+20}{6} =6
\\ \\x_{2}= \frac{16-20}{6} =- \frac{4}{6} = -\frac{2}{3}$

The circumference of a circle that was computed when the diameter is 3cm will be 9.426cm.

<h3>How to find the circumference?</h3>

The circumference of a circle of gotten by the formula:

C = 2πr or πd

where,

r = radius

d = diameter

Since the diameter is given as 3cm, the circumference will be:

= πd

= 3.142 × 3

= 9.426cm

In conclusion, the circumference of the circle is 9.426cm.
