Answer:
52
Step-by-step explanation:
We can write this out as an equation. Let's say that the teacher's age is x. Triple the teachers age plus the students age is 163, which can be written out as:

We want to isolate the variable, so subtract 7 from both sides. This gives us:

Finally, we divide both sides by 3, giving:

So the teacher is 52 years old.
Hope this helps!
Answer:
v ≤ 2
Step-by-step explanation:
To convert radians to degrees, make use of the fact that pi<span> radians equals one half circle, or 180º.</span>
<span>This means that if you divide radians by </span>pi, the answer is the number of half circles. Multiplying this by 180º will tell you the answer in degrees.
<span>So, to convert radians to degrees, multiply by <span>180/</span></span>pi, like this:
Degrees= radians X 180/pi
