Answer:
x < 7
Step-by-step explanation:
Given
5x - 7 < 28 ( add 7 to both sides )
5x < 35 ( divide both sides by 5 )
x < 7

Answer:
x < 1
Step-by-step explanation:
x - 4 < - 3
<u>  + 4    +4</u>                        Do inverse operations by adding 4 on both sides
     x < 1
Therefore, the answer is x < 1.

The circle is open because based on the concept that in inequalities, <em>less/greater than and/or equal to (such as these ≥ ≤ )</em> signs are graphed with closed circles, while less/greater than (like these > <) signs are graphed with open circles. The direction of the arrow is moving to the left on the number line because all possible values for x would be less than 1. When graphing the inequality you would use a solid line rather than a dashed line (I had to improvise since I could not attach an image).
