Answer:
In the first step, there is an issue when distributing the -3 to the terms inside of the parentheses. When multiplying the -3 to the -5, you would get an answer of +15, not -15.
The full correct process is:
(4m + 9) - 3(2m - 5) = 4m + 9 - 6m + 15
= 4m - 6m + 9 + 15
= -2m + 24
Two 1/2 gallons would be one gallon, there is 128 ounces in a gallon.
i don't know how to help you with the model but
there is 128 ounces
Thank you for posting your math question here. The number of pages are in the book Savannah reads is 196 pages. You just need to deduct the 172 pages from 368 pages of Juan book. I hope the answer helps.
368 - 172 = 196 pages
