Amachine factory produces 2 parts per second. one shift is 10 hours long. what is the production rate, in parts per shift?

72,000 parts per shift

Step-by-step explanation:

We need to figure out how many seconds are there in 10 hours and then multiply it by 2 since 2 parts are produced per second.

Number of seconds in 10 hours:

We know 60 seconds = 1 minute AND 60 minutes = 1 hour, so there are:

 seconds in a hour

So, in 10 hours we have:

seconds

Multiplying this by 2, since 2 parts per second is the rate, we get:

parts are produced

So, in 1 shift of 10 hours, 72,000 parts are produced.

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
