Answer:
A) 18 B) 1 and a half 8) 12,000m 9) 299
Step-by-step explanation:
Since he has to pay back $72 split four ways just divide that to find out that your answer is 18
Considering there are about 4 weeks in a month give or take you can just multiply 3 by four to get your first month of $12 to everyone so then you add two more weeks which is $6 more you get your answer of a month and a half to pay $18 to each person.
If the butterfly travels 6000m in 30 seconds just double everything to get 12,000m per minute.
If you want an easier part for 9 just add 13 to 286 to find out the other number to get 299 as your answer 299-13=286
Hope this helped.
A brainliest is always appreciated.
