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:
x ≤ 435
Step-by-step explanation:
Given is the following condition.
The sum of a number and 15 is less than and equal to 450.
So, if the number is x, then we have
x + 15 ≤ 450
⇒ x + 15 - 15 ≤ 450 - 15
⇒ x ≤ 435
Therefore, the solutions of the number are either 435 or less than 435 up to negative infinity. ( Answer )
What can be proven true in the diagram is the statement in letter C. angle CGB is complementary to angle AGD. It is because they both had the same vertex which is point G. Complementary angles are angles which are equal to 90 degrees wherein when you add both angles which are obviously 45 degrees, the sum is 90 degrees.
Given dimensions of a rectangular garden are:
length = 2(x+6) feet
width = 3.5x feet
using the distributive property on length we get, length = 2x+12
Perimeter of a rectangle is 2(length+width)
So, P = 2(2x+12+3.5x)
Solving it we get,
P = 2(5.5x +12) ..............adding like terms
P = .............multiplying and adding
P = 11x+24
So, perimeter is 11x+24 feet. This value of fencing will be needed.
