-27 = -3p + 15 - 3p
Combine like terms.
-3p -3p = (-3-3)p = -6p
-27 = -6p + 15
Subtract 15 from each side to get the variable term on its own.
-27 - 15 = -6p + 15 - 15
-42 = -6p
Divide each side by -6 to find p.
p = -42 ÷ -6 = 7
Multiply 9 feet times 12 inches and you get 108 inches. Then take 108 inches and divide it by 12 sections, you get 9 inches.
Answer: Each section should be 9 inches long, or 0.75, or 3/4 feet long.
R = 16 according to the problem, so the total amount of income will be:
$20*16 + $15*(40 - 16)
= $320 + <span>$15*(24)
= </span>$320 + <span>$360
= $680
that is the income, but the expenses are $275 so the total revenue is the subtraction of those two
total revenue = $680 - $275
= $405</span>
Second quartile is another name for median, so the answer is 8. I think. I'm second guessing myself now..
