Answer:
Option C
Step-by-step explanation:
The given inequality is
5x-1 < 19 and 
Group similar terms to get:
5x < 19+1 and 
5x < 20 and 
Solve for x to get:
x < 4 and 
The correct choice is C
I have no idea what the question is so?
7x-1+7x+8+5x+2=180
7x+7x+5x+2-1+8=180
19x+9=180
19x=180-9
19x=171
19x\19=171\19
x=9
therefore,7x-1
7(9)-1
=62
therefore, 7x+8
7(9)+8
=71
therefore 5x+2
5(9) +2
=47
