Answer:
RT = 20
Step-by-step explanation:
Point S is on line segment
R------------S------------T
RS + ST = RT
Given
ST=3x-8
RT=4x
RS=4x-7,
Step 1
We find x
4x - 7 + 3x - 8 = 4x
4x + 3x -7 - 8 = 4x
7x - 15 = 4x
7x - 4x = 15
3x = 15
x = 15/3
x = 5
Step 2
We find RT
RT = 4x
x = 5
RT = 4 × 5
RT = 20
The numerical length of RT is 20
Using proportions, it is found that $147.8 billion was spent on television advertising in the previous year.
- $x, in billions, was spent on advertising expenditures on television last year.
- This year, the amount declined 4.1%, hence it is 100% - 4.1% = 95.9% of last year's amount, that is, 0.959x.
This year spending's is of 141.7 billion, hence, the equation is:



$147.8 billion was spent on television advertising in the previous year.

Answer:
1260 degrees
Step-by-step explanation:
the degree of one interior angle is 108 degrees, therefore the exterior angle is 252 degrees. there are 5 interior angles, so there are 5 exterior angles. 252*5=1260 degrees
