Kids bought a package with 2 9/ 16 lb of ground meat to make hamburgers he was he has 2/5 pound of ground meat left about how many pounds of ground meat did he use for hamburgers

The quantity of ground meat he use for hamburgers is                                   2 pounds

Step-by-step explanation:

Given as :

The total quantity of ground meat bought to make hamburgers = 2

Or, The total quantity of ground meat bought to make hamburgers = pound

The quantity of ground meat left after use = pound

Now, let The quantity of ground meat used for hamburgers = x pound

So, x = The total quantity of ground meat bought - The quantity of ground meat left

Or, x = pound -   pound

Or, x =   pound

I.e x =

∴  x = 2 pounds

Hence The quantity of ground meat he use for hamburgers is                        2 pounds  . Answer

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

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
