Insert the values in for the variables.

5 - (2 + 4 - 2)

<h3>REMEMBER: PEMDAS IS THE LAW OF THE LAND</h3><h3>P (Parentheses)</h3><h3>E (Exponents)</h3><h3>M (Multiplication)</h3><h3>D (Division)</h3><h3>A (Addition)</h3><h3>S (Subtraction)</h3><h3>Note: Do multiplication/division (and subtraction/addition) from left to right and not necessarily in the order given.</h3><h3>Let's Solve!</h3>

We have parentheses in this problem, so do all operations within the parentheses from left to right.

5 - (2 + 4 - 2)

5 - (6 - 2)

5 - (4) = 1

It's gonna be 5 - (2 + 4 -2)
according to order of operations, we have to solve inside the parentheses/brackets first (from left to right)

therefore, it will be
5 - (6 - 2)
=5 - (4)

Next, distribute the negative to the four and add normally.

= 5 - 4
= 1

Which expression has the same value as 37.4 - 54.9?
GrogVix [38]

Answer:

D

Step-by-step explanation:

In the original expression =  37.4 - 54.9 = -17.5

So, we have to solve all the equations but 1 of them has to equal to -17.5

A) -54.9 + (-37.4) = -92.3

   Remove parentheses

   = -54.9 - 37.4

Subtract the numbers

    -92.3

B) 54.9 - 37.4 = 17.5

Since 54.9 is greater than 37.4 just subtract normally

 4   14

  5  4.   9                < ------- Line up the decimal points like this

-  3  7.   4                <---------  Subtract the decimals

-----------------

   1   7   .    5       <---------- This is the final answer to B.                    

 

C)  37.4 - (- 54.9) = 92.3

   Change the sign to addition

        =37.4 + 54.9

  Add the numbers normally

  54.9

+ 37. 4

--------------

  92.3

D)  37.4 + (-54.9) = -17.5

   Change the sign to subtraction

      =    37.4 - 54.9

Subtract them normally (but as you can see you are subtracting a smaller number from a larger number so heres a trick that you can use switch the equation by putting the larger number in first like this....)

54.9 - 37.4 = 17.5 (REMEMBER the answer is not 17.5 because the original equation of D is reversed  37.4 - 54.9 so in this case your answer should be

- 17.5)

37.4 - 54.9 = -17.5

Your final answer is D because it matches 37.4 - 54.9.

Hope this helps!

If 4/15 of the candies in a bag of Skittles are red and 3/10 are yellow, what fraction of the bag are red and yellow?
prohojiy [21]

The fraction of the bag are red and yellow are 17/30.

Add the two fractions together but first rewrite the fractions with a common denominator;

4/15 = 8/30;

3/10 = 9/30;

8/30 + 9/30 = 17/30;
