Answer:

\boxed{=384}

Step-by-step explanation:

<u><em>I'll give you a hint. You had to used pemdas stands for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract that came from left to right.</em></u>

First you had to multiply and divide from left to right.

21-5+24/3+90*4

21-5+8+90*4

90*4=360

21-5+8+360

Then you add and subtract from left to right.

21-5=16

16+8+360

16+8=24

24+360=384

Final answer: \boxed{=384}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

According to Order of operation, we perform: Divide then multiplication then subtraction, then sum.

In short, Your Answer would be Option C) 24To remember use PEMDAS P=parenthesis E=Exponents M=Multiply D=Divise A=Addition S=Subtraction Since you do not have parenthesis or exponents you must first multiply / 3

GOOD LUCK AND HOPE IT HELPS U

Use a inequality symbol to compare -3x+7 -10-2
abruzzese [7]
Hey there,

Let's remember that a (inequality symbol) is things like (<), (>), (≤),(≥), (≠).

So, I believe that (-3x+7) and (-10-2) are separate. So we will find that out :)

Let's first do (-3x+7). As simplifying this expression here, we take that "x" of for a while and just stick to (-3+7). 

    -3
+   7
______
     4

Let's bring that "x" back, and the answer would be 4x for a while.

So far, 4x is the answer.
_____________________________________________________________

Now, Let's work on the other side.

We are talking about (<span>-10-2)

    -10
-      2
_______
</span>     -12

So, by solving the answer to (-10-2), we got -12.

So, let's determine what is greater . . . . . 

What \ is \ greater?

-12 or 4.

-12 is on the negative side, and the number 4 is positive. This would conclude that 4 is great than -12.

Your correct answer would look like . . . 

<span>(-3x+7) > (-10-2)
</span>
I really hope this helps you alot.
