Answer: 72
<u>Step-by-step explanation:</u>
There are 9 students to choose from to go the library. After that person is chosen there are 8 students remaining.
First student and Second student
9 x 8 = 72
The answer is 1.58 m/s, That is the speed traveling 400m in 253 seconds!
21 divided 3 = 7
So your hourly wage was $7
First if b=7 then multiply 5x7=35. then if v=4 multiply 4x8=32. Finally, add 35+32 to get 67
the cost is $67
This is showing what you asked i believe.
