How to round to the nearest cent

DaniilM [7]

Since there are 100 cents in a dollar, routing to the nearest cent would be rounding to the nearest hundredth. In order to do that you would solve to the thousandths place the use that number to round up or down to the nearest hundredth.

For example:

If a dozen roses cost $12.35, how much does each rose cost?

12.35 ÷ 12 = 1.029

The 9 is in the thousandths place. If it is 5 or higher we round the hundredths place up, so our answer is each rose costs 1 dollar and 3 cents ($1.03)

How do i solve x^2+7x=3x

valina [46]

To solve, you must make one side of the equation equal to zero. We can do this by subtracting 3x on both sides of the equation.

<span>x^2 + 7x = 3x
</span> - 3x -3x

x^2 + 4x = 0.

Then we substitute the equation into the quadratic equation.

$\frac{-b+- \sqrt{b^2-4ac} }{2a}$

Where a = 1 b = 4 and c = 0

$\frac{-(4)+- \sqrt{(4)^2-4(1)(0)} }{2(1)}$

We first solve whats inside the square root.

$\frac{-(4)+- \sqrt{16} }{2(1)}$

$\sqrt{16} = 4$

Now we solve for -4 and 4.

$-4 - 4 = -8$
$-4+4=0$

Then divide both answer by 2

$\frac{-8}{2} = -4$
The division of any by zero is zero

So the answer are x = -4 and x = 0
