Which is equal to 8^-10/8^5 ?
makkiz [27]
8^{-10} can be converted into \frac{1}{ 8^{10} } , and applying this to 8^{-5} can see that

\frac{ \frac{1}{ 8^{10} } }{ \frac{1}{ 8^{5} } }

This gives us 

\frac{ 8^{5} }{ 8^{10} }  =  \frac{1}{ 8^{5} } = 8^{-5}

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 for x, x^2-3x-5=0
Sophie [7]

Okay so for this one, we have to isolate our X.Lets start by moving the negative 5 on the other side of the equal sign. Remember to not mix a number that is with an X with a normal number (in this case it would be the -3x and the -5). So in putting our -5 on the other sign it becomes positive. Here’s what we have: x^2-3x=5. x^2 is the same thing as 2x.So now you have to minus 3x off of your 2x. This gives us -1x, but can just be put as -x. So now we have -x=5. You’re answer could either be 5 or -5 if you decided to divide it by -1 seeing as your -x is technically -1.

Lilit [14]

X = 8

18-(2x8) = 18 - 16 = 2

8+9=17

Perimeter = 2x width + 2x length

Width = 2x17 =34 34 + 4 = 38
