Short Answer: n = 5
The chords bear the relationship of (in this case)

18*(n + 1) = 9 * (n +7) Remove the brackets
18n + 18 = 9n + 63 Subtract 9n from both sides.
18n - 9n + 18 = 63
9n + 18 = 63 Subtract 18 from both sides.
9n = 63 - 18
9n = 45 Divide by 9
n = 45/9

A cake recipe requires 3 and 1/4 cups of flour for 13 servings and 4 and 1/2 cups of flour for 18 servings. How much flour is re

gregori [183]

So, each serving requires:

3 1/4 divided into 13:
$3\frac{1}{4} /13= \frac{13}{4} * \frac{1}{13} = \frac{1}{4}$

let's check from the second information:
4 2/4 divided into 18:
$4\frac{2}{4} /18= \frac{18}{4} * \frac{1}{18} = \frac{1}{4}$

so for 28, we need:

$\frac{1}{4} *28= \frac{28}{4} = \frac{14}{2} = 7$

we need 7 cups of flour!
