each unit uses a chip 3/32 inches long how many units can be made if i have chips that are 9/16 inches long
Vikentia [17]
If you do 9/16 / 3/32 you can change that into 9/16 x 32/3 and cross multiply which gives you 512/27. And that equals 18.96 which you can round to 19. So you would be able to make 19 units if you use the 9/16 chips

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.
