3) David goes into a candy store with $5.00. He buys 9 peppermints for $0.15

yuradex [85]

<h3>Write an equation that will match the story problem</h3>

$x=(5 - (9 \times 0.15) ) \div 0.25$

Solution:

Given that,

David goes into a candy store with $5.00

Total amount with David = $ 5

He buys 9 peppermints for $0.15 each

And some sour candies. each sour candy costs $0.25

The equation is:

Let the number of sour candies bought be "x"

Then,

Remaining amount after buying pepper mint = $5 - 9 \times 0.15 = 3.65$

Each sour candy cost $0.25

Now the number of sour candies bought is:

$3.65 = 0.25 \times x$

x = 14.6

Thus david can buy 14 sour candies

Thus the equation that will match the story problem is:

$x=(5 - (9 \times 0.15) ) \div 0.25$

Where, "x" means number of sour candies bought

Consider the quadratic equation x 2 = 4x - 5. How many solutions does the equation hase?

lara [203]

Answer:

The equation has 2 non real solutions.

Step-by-step explanation:

Given:

$x ^2 = 4x - 5$

To Find:

The solutions of the equation = ?

Solution:

Lets find the solution using the quadratic equation formula

$x ^2 = 4x - 5$

$x^2-4x +5 = 0$

$x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}$

Here

a = 1

b =-4

c = 5

Now Substituting the values,

$x = \frac{-(-4) \pm \sqrt{(-4)^2-4(1)(5)}}{2(1)}$

$x = \frac{4\pm \sqrt{16-20}}{2}$

$x = \frac{4\pm \sqrt{-4}}{2}$

$x = \frac{4\pm \sqrt{4}\times \sqrt{-1}}{2}$

$x = \frac{4\pm 2 \sqrt{-1}}{2}$

$x = \frac{4\pm 2i}{2}$

$x= \frac{4+2i}{2}$ $x= \frac{4-2i}{2}$

x= 2 + i x= 2-i
