Which expression has the same value as 37.4 - 54.9?

GrogVix [38]

Answer:

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!

X+2y=-1 and 4x-4y=20 solve by substitution

Illusion [34]

To do this problem you would first need to factor out a variable, which in this case I would want to do the first equation because it is isolated. Now the equations would look like this:

x = -2y - 1

4x - 4y = 20

Since we know that x is now equal to -2y - 1 we can plug it in to the x value in the second equation:

4 (-2y -1) - 4y = 20

-8y -4 - 4y

-12y - 4 = 20

-12y = 24

y = -2

Now that we know the y value plug the y value to one equation to find the x, I will be using the first equation

x + 2(-2) = -1

x - 4 = -1

x = 3
