Answer:

180 pages

Step-by-step explanation:

let x be the number of pages in the book , then

\frac{7}{9} x + 40 = x ( multiply through by 9 to clear the fraction )

7x + 360 = 9x ( subtract 7x from both sides )

360 = 2x ( divide both sides by 2 )

180 = x

The total number of pages in the book is 180

Greg made 27 ounces of potato salad to serve to 10 people at a picnic if each serving is the same size how much potato salad wip
kirza4 [7]

Answer:

Each person will get 2.7 ounces of potato salad.

Step-by-step explanation:

We are given that;

Total ounces of potato salad Greg made = 27 ounces

Number of persons to be served = 10 people

Now, we are told that each serving is the same size, thus it means each person will receive same size of potato salad.

Thus,

the amount received by each person = Total ounces of potato salad Greg made/total number of persons to be served.

So,

the amount received by each peron

= 27/10

= 2.7 ounces

Thus,

Each person will get 2.7 ounces of potato salad.
