Answer:

Step-by-step explanation:
Let c be the number.
We are asked to write an expression for given verbal description.
7 times the number c would be
.
Two less than seven times a number means 2 subtracted from
.
Two less than seven times a number c would be
.
Therefore, our required expression would be
.
Answer:

Step-by-step explanation:
We have to use the slope formula: m = slope
(x1, y1) = coordinates of the first point in the line
(x2, y2) = coordinates of the second point in the line
Here, we'll plug into our given points to give; 
Solving this, we get,
, but we're not done, as this fraction can be reduced.
Diving both sides of the fraction by 2, we get our final answer of
.

Answer:
100<x<500
Step-by-step explanation:
The third side cannot exceed the others added up so x is less than 500, due to the laws of triangles.
If you subtract 300-200, you get 100, so x has to be greater than 100.
x is greater than 100 but less than 500
Therefore the answer is...
100<X<500
The laws of triangles state that a triangle has to be greater than the other two edges subtracted, and less than the other two edges added.
I hope this helps!!!
