Answer:
-1>x
Step-by-step explanation:
-5x - 15 > 10 + 20x
Add 5x to each side
-5x+5x - 15 > 10 + 20x+5x
-15> 10+25x
Subtract 10 from each side
-10 - 15 > 10-10 + 25x
-25> 25x
Divide each side by 25
-25/25> 25x/25
-1>x

If f(4a) = 80, then the value of "a" is 4.2
<em><u>Solution:</u></em>
Given that cost for the olive oil used to fill the containers on the tables in an Italian restaurant is given by the function:
f(x) = 5x – 4
where "x" represents the number of quarts of olive oil
f(x) represents the quarts of oil used
To find: value of "a" when f(4a) = 80
Substitute x = 4a in given function
f(4a) = 5(4a) - 4
80 = 20a - 4
20a = 84
10a = 42
a = 4.2
Thus the value of "a" is 4.2

Answer:
504 ft
Step-by-step explanation:
Perimeter = 2(width) + 2(length)
Convert yards to feet
1yard=3feet
8yards=?
8*3/1 = 24feet
84 = 2(w) + 2(24)
84 = 2w + 42
84 - 42 = 2w
42 = 2w
w = 21
Area = 1 * w
= 21 * 24
= 504 ft
