Step-by-step explanation:
you first need to convert 9 hours into minutes:
9*60=<u>5</u><u>4</u><u>0</u> minutes
162 jumps ---in--- 540 minutes
? jumps ---in--- 10 minutes
?= (10*162)/540
?= 3
You would first subtract 5*8 from 168 which would leave it at 128 then divided it by 8 and then you'll end up with 16 so each tree cost 16$
Multiply the tops and multiply the bottoms
Aka
5*21
-------
7*25
And simplify
Step-by-step explanation:
AC= 8x-14
AC+14=8x
x=(AC+14)÷8
EC=2x+11
EC-11=2x
x=(EC-11)÷2
