Next month 486 students, teachers, and parents are going on a field trip to the zoo. Each bus holds 35 people. How many buses are needed for the trip?

14 buses

Step-by-step explanation:

When you divide 486 and 35 it comes out to about 13.88

therefore you would have to round up so some arent left behind

14 buses

Step-by-step explanation:

13 buses will each hold 35 people and 1 bus will hold 31 people. 35x13=455 add the 31 people that will be on one of the buses and the total of people riding the buses to go to the trip will be 486.

250

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
