I got 16.8 , but she’ll need roughly 17 gallons of paint :)
how i did it :
1. so you know she’ll need 4/5 per book case, and there are 16 bookcases.
2. So you do 16 x 5, then you get 84
3. and you divide 84 by 5. and you’ll get 16.8, that’s how many gallons of paint she needs
X is 12, I did this question to someone else before
When dividing by a negative number, you switch the signs.
First analyze your question. Barbara has a goal to read 45 minutes every day. If she meets her goal, how many minutes will she have read in 360 days?
So....
360*45=16,200
The answer is D. 16,200
Good luck with your studies, I hope this helps!!
W = 3L so 64 = WL = (3L)(L) = 3 L ^2 Square root both sides. W = 8
