Why is it important that everyone follow the same order of operations when evaluating expressions?

Because if not, different people would get different answers. If the expression is evaluated without using the order of operations, the answer won’t be the same. I hope this helps!

As an example, let’s say we had 3+4x2
Without PEMDAS, we would add 3 and 4, then multiply by 2, getting 14 (the wrong answer).
With PEMDAS, we would multiply 4 and 2, then add 3, getting 11 (the correct answer!).
So if you don’t use PEMDAS, you’ll just get a different answer than you should’ve. Hope that helped!

Answer: Badwater is 282 feet below the sea level.

Step-by-step explanation:

Given: Death Valley headquarters in California is 190 feet below sea level. Badwater, America's lowest point, is 92 feet lower than Death Valley headquarters.

To find the depth of Badwater we need to add depth of Death Valley headquarters from sea level to the depth of Badwater from Death valley headquarters.

i.e. The Depth of Badwater from sea-level = 190 feet +92 feet

= 282 feet

Hence, Badwater is 282 feet below the sea level.

Which graph correctly solves the system of equations below? y=-x^2+1 y=x^2-4

KIM [24]

Red line shows
y=x^2-4 , cause it's going through point (0,-4)

So blue line shows
y= -x^2+1 Point (1,0) belong to it , moreover x factor is negative , so the arms of parabola will go down

Have nice evenig :)

larisa [96]

Answer:

$1.12

Step-by-step explanation:

12÷3=4

1 box of markers is $2.50, Multiply $2.50 by 3 and you get $7.50. 12- $7.50= $4.50. $4.50÷ 2= $2.25. $2.25÷2= $1.12

Not 100% but i'm pretty sure this is the answer. Hope this helps. ( if i'm wrong sorry its 2:30 am)
