Answer:
x = 16
Step-by-step explanation:
(x +4) : (x +12) :: (x-1)(x +5)
As they are in proportion,
Product of means = Product of extremes
(x + 4)* (x +5) = (x + 12)(x - 1) {Use FOIL method}
x*x +x*5 +4*x + 4*5 = x *x + x*(-1) +12*x + 12*(-1)
x² + <u>5x + 4x</u> + 20 = x² <u>- x +12x</u> - 12 {Now combine like terms}
x² + 9x + 20 = x² + 11x -12
x² + 9x +20 - x² - 11x = -12
x² - x² + 9x - 11x = -12 - 20
0 - 2x = - 32
-2x = -32 {Divide both sides by -2}
x = -32/-2
x = 16
Answer:
Step-by-step explanation:
Answer: 2.4 as a decimal or 12/5 in fraction form
The correct answer is letter C.
The reason is because there are 12 cake donuts out of the 36 total. This is a simple ratio of 1 to 3. This means one out of every 3 people would get a cake donut. If there are 12 people, this is 4 groups of 3, so one person from each group of 3 is 4 people.
