What value of x makes this equation true?

Mathematics
1 answer:
Alex73 [517]3 years ago

Answer:

x=9/4=2.25

Step-by-step explanation:

The model is essentially saying:

3(-x)+10(1)=5(x)+8(-1)

Simplify:

-3x+10=5x-8

Subtract 5x from both sides:

-8x+10=-8

Subtract 10 from both sides:

-8x=-18

Divide both sides by -8. The negatives cancel:

x=18/8

Reduce:

x=9/4=2.25

And we're done!

MrRissso [65]

Answer:

Step-by-step explanation:

I know that there is a zero and a 1 involved in this somewhere. The  only answer I can get which is a bit of a cheat, is

1^0! = 0!^1

These are not exactly the same thing. The trouble is that they are equal. There is a difference between "not the same thing" and "equal."

If I think of something else, I'll put it in a comment.

Which statement is true
loris [4]

Answer:


Step-by-step explanation


You must find the common denominator for all of them.  


A is correct. 13 x 2 is 26 and 14 x 2 is 28. Therefore, 13/14 is greater than 25/28.


B is not correct. 4 x 5 is 20 and 9 x 5 is 45. 4/9 is actually less than 21/45.


C is not correct. 5 x 2 is 10 and 6 x 2 is 12. 5/6 is actually less than 11/12.


D is not correct. 4 x 5 is 20 and 5 x 5 is 25. 4/5 is actually less than 8/25.
