Answer:
X = all #'s
why?
6x+10+10x < 4(4x+3)
Combined liked terms
16x + 10 < 16x +12
you can see that there is X on both sides and the lowest one has a +10 and the highest has a +12 so it will always be greater by 2
undeterminate (all real numbers are a solution)
Step-by-step explanation:
1) multiply 4 by 4x and 3
6x + 10 + 10x < 16x + 12
2) added up the terms with x
16x + 10 < 16x + 12
3) add at the two members -16x
10 < 12
4) notice the 10 is ever < 12, so the inhequality is undetermined
15+2a
7+a+8+a=15+2a
So you can play? I guess...
Think it is A as 4x20=80.
