Abathtub fills at a constant rate. the amount of water in the tub increases by 1/2 gallon evert 1/10 minute. what is the unit rate at which the tub fills?

5 gallons per minute

Step-by-step explanation:

A bathtub fills at a constant rate.

The amount of water in the tub increases by gallon every minute.

Unit rate: The amount of gallons fill bathtub in unit minute.

We are given rate is constant.

Therefore,

Hence, The unit rate is 5 gallons per minute.

5x+10 is the correct one

hope this

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.
