33.3 repeating percent
You set up a proportion
6/18 = x/100
100x6= 600
600÷18 = 33.3 repeating
I got 6.49204 but you will need to round so D 6.5
I added all of the numbers up
Answer:
33 newspapers per 1 pile.
Step-by-step explanation:
33+33+33=99
X = 47 + 9y
xy = 1860
y(47 + 9y) = 1860
47y + 9y² = 1860
9y² + 47y - 1860 = 0
> using a quadratic equation solver on a calculator but you can also use the quadratic equation = [-b+/- √(b²-4ac)]/(2a)
> only integer solution is x = 12
12y = 1860
y = 155
integers are 12 and 155
