Answer:
Step-by-step explanation:
#6
a n
---- = ---- Solve for a. Note that if we multiply both sides of this equation by
m p n
m, we get a = m * ----
p
m*n
and this simplifies to a = mn/p or a = ---------
#7 Solve mx = np for x. We want to isolate x on the left side. Dividing
both sides by m isolates x on the left and adds the divisor m on the right:
np
mx = np => x = ------
m
#8 Solve c - x = d + r for x We want -x alone on the left side. Accomplish this by subtracting c from both sides, obtaining:
-x = d + r - c. Now multiply both sides by -1, obtaining x = -d - r + c
You have to find the unit rate, which in this case means the amount of fish you need per serving of soup.
If 16 oz of fish makes 24 servings, then 16/24 oz = 2/3 oz makes 1 serving.
Now multiply both quantities by 10, so that 10 servings require 20/3 oz ≈ 6.67 oz of fish.
A more direct way to do this is to solve for <em>x</em> in the following equation:
(16 oz fish) / (24 servings) = (<em>x</em> oz fish) / (10 servings)
Then (omitting units)
<em>x</em> = 10 • 16 / 24 = 20/3
Let x be the number of pages of advertisements.
Write a proportion from the table:
of a page of advertisment - 5 pages in a magazine
x pages of advertisment - 98 pages in a magazine,
then
![\dfrac{\dfrac{2}{3}}{x}=\dfrac{5}{98}.](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cdfrac%7B2%7D%7B3%7D%7D%7Bx%7D%3D%5Cdfrac%7B5%7D%7B98%7D.)
Find x:
![x=\dfrac{\dfrac{2}{3}\cdot 98}{5}=\dfrac{196}{15}=13\dfrac{1}{13}.](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B%5Cdfrac%7B2%7D%7B3%7D%5Ccdot%2098%7D%7B5%7D%3D%5Cdfrac%7B196%7D%7B15%7D%3D13%5Cdfrac%7B1%7D%7B13%7D.)
Answer: 13 whole pages and
of 14th page are advertisments, so 14 pages contain advertisments.
