It took you 15 minutes to read 8 pages of your history book. At that rate, how long will it take you to read 10 more pages?

18.75 minutes.

Step-by-step explanation:

Since it takes 15 minutes to read 8 pages, we divide 15 by 8 to get the minutes per page. We get 1.875 minutes per page. Multiply that by 10 minutes and you get 18.75 minutes.

I got 18.75 minutes (Don't judge if this doesn't work, I'm still in Middle School)

Step-by-step explanation:

15/8 = 1.875

1.875 x 10 = 18.75

Hope it helps! (or not I'm very dumb)

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.
