1/2(62)+5? explain

OpenStudy (anonymous):

explain what?

OpenStudy (anonymous):

Alright, so let's use Order of Operations to solve this. First, let's use the parentheses first. So multiply 62 by 1/2 and then add 5.

OpenStudy (anonymous):

idk how to solve like the 1/2 part i know how to do the rest just not the 1/2

OpenStudy (anonymous):

Multiply 1/2 by 62. So take half of it.

OpenStudy (anonymous):

that means times \[\frac{1}{2}\times 64\]

OpenStudy (anonymous):

62 divided by.5?

OpenStudy (anonymous):

No, 62 * 0.5

OpenStudy (anonymous):

64*

OpenStudy (anonymous):

ohh okay

OpenStudy (anonymous):

im not good at fractions

OpenStudy (anonymous):

Parentheses means Multiply.

OpenStudy (anonymous):

so the answer is 31?

OpenStudy (anonymous):

but don't forget to add the 5 :)

OpenStudy (venomblast):

the question can be confusing for some people because to me that is just saying 2 * 64.

OpenStudy (anonymous):

Where do you get 64???

OpenStudy (anonymous):

so 36?

OpenStudy (anonymous):

Yes.

OpenStudy (anonymous):

oh okay thanks :)

OpenStudy (anonymous):

wait

OpenStudy (anonymous):

1/3(261) - 9?

OpenStudy (anonymous):

@*Shadow*

OpenStudy (anonymous):

So just use the same process.

OpenStudy (anonymous):

You can actually divide 261 by 3.

OpenStudy (anonymous):

So divide it by the denominator and multiply that result as a numerator. Then subtract 9.

OpenStudy (anonymous):

oh so hold on let me solve it and then you check it

OpenStudy (anonymous):

87?

TheSmartOne (thesmartone):

PEMDAS

OpenStudy (anonymous):

i hate pemdas

TheSmartOne (thesmartone):

Do the multiplication first and then subtract...

TheSmartOne (thesmartone):

1/3(261) - 9? So first divide 261 by 3 and finally jsut subtract it by 9...

OpenStudy (anonymous):

so 3x261?

OpenStudy (anonymous):

i just dont get the 1/3 part i hate fractions

TheSmartOne (thesmartone):

no 261/3

OpenStudy (anonymous):

and thats 87?

TheSmartOne (thesmartone):

\[\frac{ 261}{ 3 }\]

OpenStudy (anonymous):

87?

OpenStudy (anonymous):

is the answer right

OpenStudy (anonymous):

its not 87 :(

OpenStudy (anonymous):

Yea, 87.

OpenStudy (anonymous):

And then subtract 9 :)

TheSmartOne (thesmartone):

yea 87-9=??

OpenStudy (anonymous):

TheSmartOne (thesmartone):

It equals to 78....

OpenStudy (anonymous):

ohhh okay well i have more i need help with

OpenStudy (anonymous):

1/3z-11?

OpenStudy (anonymous):

oh z=144

TheSmartOne (thesmartone):

So 144/3 then subtract 11....

OpenStudy (anonymous):

hmm so its hold on

OpenStudy (anonymous):

37?

OpenStudy (anonymous):

TheSmartOne (thesmartone):

37 is the correct answer...

OpenStudy (anonymous):
