Avan has room for six students and two teachers. how many vans are needed for a total of 48 students and 16 teachers

You would need 8 vans because:

48/6 = 8

16/2=8

Plus, if you add the number of students and teachers together it equals 64. Then divide it by the number of people who can fit into the van, which is 8.

64/8=8 vans

there will be needed 10 buses so other people can fit in

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
