The local cafe uses 510 cups of mixed vegetables to make 1000 quarts of beef barley soup. each quart of soup contains the same amount of vegetables. how many cups of vegetables are in each quart of soup.

.510 cups

Step-by-step explanation:

510 cups            x cups

       =

1000 quarts     1 quart

using cross products

510 * 1 = x * 1000

divide by 1000

510/1000 = x

.510 cups

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
