The answer is 24. it works like this. you subtract 2 from 12 and get 10. then add 5 to 10 to get 15. then subtract 2 from 15 and get 13. 13+5 is 18. and so on
Answer:
12 feet
Step-by-step explanation:
30 divided by 5= 6
6 times 3= how far youve already swam(18 feet)
6 times 2= how far you have left(12 feet)
None of them are equivalent because
= 3(-2)+7
= -6 +7
= 1
