4/5w-12=2/3w<br> what is the step by step answer to those equation?
Mariulka [41]
Kulay, there is no such thing as a "step by step answer" here.  You seem to want a "step by step solution."

I must assume that by 4/5 you actually meant (4/5) and that by 2/3 you meant (2/3).  Then your equation becomes:

(4/5)w - 12 = (2/3)w. 

The LCD here is 5*3, or 15, so mult. every term by 15:

12w - 180 = 10w.   
Add 180 to both sides, obtaining 12 w - 180 + 180 = 10w + 180.     

Then 12w = 10w + 180.  Simplifying, 2w = 180.    What is w?

I need help with someone explaining how to find the range of this! This course didn’t explain anything!
zaharov [31]

Answer:

(-infinity,3), D

Step-by-step explanation:

3 if x is greater than or equal to 1 is nothing. That leaves us with h(x)=2x+1 if x<1. If you substitute in 1 for x, you get 3, but of course that isn't possible, so the range is (-infinity,3), which is D.
