dmitriy555 [2]

Answer:

$360 on game console

$480 on tv

$1440 before spending money

x - 1/3x - 1/4x = $600

12/12x - 4/12x - 3/12x = $600

5/12x = $600

x = (12/5)($600)

x = $1440

Game Console = (1/4)(1440) = $360

Hope this helped!

Answer: -13, -12.9

Step-by-step explanation:

pull out that HANDY DANDY calculator dog because we are about to go on a MATH ADVENTURE oh yea.

ok first make sure it is a reasonably good calculator but you can even use a calculator on your chromebook, maybe an online one? we need one that gives us PARENTHESES.

ok now you are going to want to input into this calculator, $(335 / 2)$ in other words 335 divided by 2. what do we get? we get

$167.5$

ok cool WE ARE MAKING PROGRESS HERE!!!

now i want you to look for the square root button, it looks like a radical like this

$\sqrt[2]{}$ or MAYBE IT DOESNT EVEN HAVE THE 2 and it is just: $\sqrt[]{}$

and press it, it should give you the square root but we want to find $\sqrt{167.5}$

and we get.....

$12.942...$

MY GOD THAT IS A SUPER LONG NUMBER! but its ok we only need 3 digits after the decimal. now notice that there is a negative sign behind that radical. thats radical, dude, ok now we have $-12.942...$

if we round to the nearest INTEGER then we need to round to the nearest WHOLE NUMBER which is

$-13$

and the nearest TENTH is one number after the decimal place so it would be...

$-12.9$

SURFS UP DUDE

P.S. i mention the parentheses because you can even do $\sqrt{(335/2)}$ (press square root button then opening parentheses then 335 / 2 then close parentheses and hit equal sign or ENTER) but dont forget that EPIC NEGATIVE SIGN!!!!!!!
