The Math Club is selling shirts to raise money for a Pi Day Convention. Short sleeve shirts are $5 and long sleeved shirts are $
Sladkaya [172]
<h2>Answer:</h2>

# short sleeved shirts sold  is 50

# long sleeved shirts sold 35

<h2>Step-by-step explanation:</h2>

First, you need to set up the equation.

(5x)+10*(85-x)=600

5x+850-10x=600

-5x+850=600

-5x=600-850

-5x=-250

x=50


After you solve the equation, you know, that 50 short sleeve t-shirts were sold. Now, you need to find out how many long sleeved t-shirts were sold. 85-50=35. Now you know, that there were 35 long sleeved t-shirt sold.

You can now check your answers. 50*5 + 35*10=600

That is correct.

I hoped I helped you. I will be really glad, if you mark my answer with brainliest.

Solve x2 – 5x – 24 = 0 by completing the square
boyakko [2]

The solutions of the equation x² – 5x – 24 = 0 will be 8 and -3. Then the correct option is D.

<h3>What is a factorization?</h3>

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The quadratic equation is given below.

x² – 5x – 24 = 0

Then the factor of the equation will be

       x² – 5x – 24 = 0

x² – 8x + 3x – 24 = 0

x(x – 8) + 3(x – 8) = 0

       (x – 8)(x + 3) = 0

                          x = 8, -3

Then the correct option is D.

More about the factorization link is given below.
