The answer to the question is A. What you do, is first get rid of the fraction by multiplying everything by 5. You should then have 100-4x>=80. Now subtract 100 from each side. Then what your going to want to do is divide each side by -4. Don’t forget that when you divide by a negative number and there is greater than or less than sign, the sign automatically changes the opposite way. 20-4/5 x>=165(20-4/5 x)>=(16)5100-4x>=80-4x>=-20x<=5 A....
