Answer:
8 hours
Step-by-step explanation:
if 189 miles= 7 hours. what about 216 miles.you cross multiply
3 dozen= 36, you need 720.
720/36= 20.
This means you'll need to scale up the recipe to a factor of 20. In other words, you'll need to multiple the amount of each ingredient required by 20 in order to have enough cookies for 360 people to each have two.
To find out how much each book cost first we will subract to find out how many 2 books cost. Then we will divide. last but not least we will check our wok. Lets do it:-
30 - 8.95 = <span>21.05
</span><span>21.05 - 7.25 = 13.80
</span>
CHECK OUR WORK:-
13.80 + 7.25 = 21.05
21.05 + 8.95 = 30
We were RIGHT!!!
Now lets divide:-
13.80 ÷ 2 = 6.90
1 book costs $6.90.
CHECK OUR WORK:-
6.90 × 2 = 13.80
We were RIGHT!!!!
So, 1 book costs $6.90.
Hope i helped ya!!
