Answer:

$d\geq 5\\\\w<7\\\\a\leq 4$

Explanation:

For each you have to look at three things - the direction of the arrow, if the circle is filled in, and the number the point is located on.

If the arrow is pointed right and the numbers are increasing, you use the greater than sign (>).

If the arrow is pointed left and the numbers are decreasing, you use the less than sign (<).

If the circle is filled in, it means you use the greater than or equal to (≥) less than or equal to signs (≤).

For the first inequality, the arrow is pointing right, the circle is filled in, and the point is on five so the inequality is
$d\geq 5$ .

For the second inequality, the arrow is pointing left, the circle is not filled in, and the point is on seven so the inequality is
w<7 .

For the third inequality, the arrow is pointing left, the circle is filled in, and the point is on four so the inequality is
$a\leq 4$ .
