Answer:
it should be a,c,e,d
Step-by-step explanation:
1600<2570-125.5x<2000 subtract 2570 from all terms...
-970<-125.5x<-570 divide all terms by -125.5 (and reverse signs because of division by a negative!)
7.73>x>4.54 and x is months since January, and since months can only be integers...
x=[5,7]
So January + 5, 6, and 7 respectively are the three months that satisfy the equation...
June, July, and August.
5 and 6 because 5 1/4 = 5.25.
5.25 is less than 6, but greater than 5.
Yes when adding a negative you flip the inequality.
