Answer:
The number will be 
Step-by-step explanation:
Let us assume the number as
.
Given:
⇒
less than twice a number that will be
, which is equal to half the difference of three times the number and 13
We have to find the number.
Solution:
The difference of three times the number and 13 could be represented as : 
The value be equal to
of this
⇒ 
As we can see here,
- That we got a equation ⇒

Now, we can solve the above equation:

We have multiply both sides by
⇒ 
then, ⇒ 
⇒
Hence we can say that number which was assumed as
will be

Answer:
6:11
Step-by-step explanation:
You'd use the equation y2-y1/x2-x1
0-(-3)/-7-5 = 3/-12 = -1/4
So -1/4 would be the slope
m= -1/4
