ASAP PLEASE—-Mackenzie placed 5 pieces in the puzzle for bc every 4 pieces her little brother placed. If Mackenzie’s little brother placed 20 pieces in the puzzle, how many pieces did the puzzle have altogether

45 pieces.

Step-by-step explanation:

First, if the ratio is 5 : 4, then is you multiply 4 x 5 to get 20, you need to multiply 5 x 5 to get 25.

Second, 20 + 25 = 45 which is the total amount of puzzle pieces.

Hope this helps!

problem:

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

f(5/2) = 10/3

i hope this !
