Let p represent # of physics texts sold
Let m represent # of maths texts sold
Therefore we have p = m - 60 | because physics texts sold are less than maths by 60
Total sold = 206 = m + p | recall that p = m - 60
We then have 206 = m + m - 60
206 = 2m - 60 | adding 60 to both sides, we have
206 + 60 = 2m | dividing both sides by 2
266/2 = 2m/2
Therefore, m = 133 texts
and p = m - 60 = 133 - 60 = 193
2 because it is the only degree there in the problem

Answer:
The result of -1/4 - 1249 is -4997/4
Step-by-step explanation:
Doing the basic math on the given expression:
Given expression = -1/4 - 1249
= (-1 - 4996) / 4
= -4997/ 4
= - 1249.2
We know that the Pythagorean Theorem is a² + b² = c². First lets start with 6, 8, and 10. There is a simple way to know that these are Pythagorean triples. They make up what is called a 3-4-5 triangle. 3 x 2 is 6, 4 x 2 is 8, and 5 x 2 is 10. Next 5, 12, and 13 are Pythagorean triplets because 5² + 12² = 13². Because both of these form right triangles, we know that they are Pythagorean triplets.
Hope this helps :-)
