1.
Checking the numbers that are greater than 10 in this set, we have:
11.2 and 12
2.
The numbers in this set that are lesser than or equal 9 are:
0, 4.5, 5 and 9
3.
Solving the inequality, we have:
[tex]\begin{gathered} x+3>10 \\ x>10-3 \\ x>7 \end{gathered}[/tex]
Three values greater than 7 are:
8, 9, 10
4.
Solving the inequality, we have:
[tex]\begin{gathered} 3x<15 \\ x<\frac{15}{3} \\ x<5 \end{gathered}[/tex]
Three values smaller than 5 are:
4, 3, 2
5.
Solving the inequality, we have:
[tex]\begin{gathered} \frac{x}{5}\ge2 \\ x\ge2\cdot5 \\ x\ge10 \end{gathered}[/tex]
Three values greater than or equal 10 are:
10, 11, 12
