Your friend has owned a dog for nine years this is one year less than twice as long as he owned a cat how long has your friend o
Oduvanchick [21]

Answer:

He owned Cat for 5 years.

Step-by-step explanation:

Given: Owned dog for 9 years.

           Dog owned year is one year less than twice as long as he owned a cat.

Lets assume the years that cat has been owned be "x".

Now, finding the number years that Cat hes been owned.

As given, Dog owned year is one year less than twice as long as he owned a cat.

∴ using equation to find the Cat´s owned years.

⇒ 2x-1= 9

adding 1 on both side.

⇒ 2x= 10

dividing both side by 2

⇒x= \frac{10}{2}

∴x= 5\ years

Hence, Cat has been owned for 5 years.

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.
