olga_2 [115]

Answer:

  60

Step-by-step explanation:

Let s represent the number of stickers Sophia has. Then the number Ethan has is (2/3)s. The transfer of 16 stickers can be described by the equation ...

  (s -16)/(2/3s +16) = 1/2 . . . . . sophia/ethan = 1/2 after the transfer

  2s -32 = 2/3s +16 . . . . . . . . .cross multiply

  4/3s = 48 . . . . . . . . . . . . . . . add 32-2/3s

  s = (48)(3/4) = 36 . . . . . . . . .multiply by 3/4

Together, the total number of stickers held is s +(2/3)s = (5/3)s.

  5/3s = (5/3)(36) = 60 . . . . . total of Sophia's and Ethan's stickers

Together, Sophia and Ethan have 60 stickers.

4x - 5= 2(2x - 1) -3
Alekssandra [29.7K]

Answer and Step-by-step explanation:

Solve for x.

Distribute the 2.

4x - 5 = 4x - 2 - 3

Combine like terms

4x - 5 = 4x - 5

Add 5, and subtract 4x.

0 = 0

There are infinitely many solutions, meaning any value plugged in for x will result in the equation being true.
