Answer:
2 tenths
Step-by-step explanation:
In decimal form: 2.2
You can see that in the tenths place, there is a 2, so 2 tenths.
The inequality should read:

Subtract 2 from all the terms:

Divide all the terms by -5 to get x by itself (note that you flip the inequality signs as you divide by a negative):

The inequality is 2 ≤ x < 8.
A closed dot represents ≤, and an open dot represents <. Since x can represent all values between 2 and 8, you will shade in between 2 and 8 on the number line. x is greater than or equal to 2, so there will be a closed dot on 2. x is less than 8, so there will be an open dot on 8.
The answer is 'number line with a closed dot on 2 and an open dot on 8 and shading in between'.

Step-by-step explanation:</h2>
A tangent is a line that passes through exactly one point on a circle. For any point on a circle, the radius and tangent line through that point are always perpendicular to each other making a right angle. If two triangles touch each other externally, then there will be 3 lines making right angle with radius of the circles at the point of intersection of circle and tangents. These three tangent lines are shown below. They are the black, blue and green ones.
