I can’t find the answer please help

Answer 1

Answer: A

Explanation:

81 - 1 1/5x
`\leq` 55 The first thing you could do is convert the mixed fraction into an improper fraction.

1 1/5 to an improper fraction is -6/5

Now rewrite the inequality as,

81 - 6/5x
`\leq` 55 Subtract 81 from both sides

-81 -81

-6/5x
`\leq` -26 Multiply both sides of the inequality by 5

-6x
`\leq` -130 Divide both sides by -6 and the sign will me flip since your divide both sides by a negative number.

x ≥ 130/6 Convert 130/6 to a mixed fraction

x ≥ 21 2/3
