Step-by-step explanation:
Answer:
each van carries 7 students
each bus carries 60 students
Step-by-step explanation:
let v = # students in a van
let b = # students in a bus
system of equations:
13v + 2b = 211
4v + 4b = 268
I multiplied the 1st equation by -2 to eliminate the 'b' terms
-26v - 4b = -422
+ <u>4v + 4b = 268</u>
-22v = -154
v = 7
substitute '7' for 'v':
4(7) + 4b = 268
28 + 4b = 268
4b = 240
b = 60
C . 100 Times Greater
Then with the magnitude being 3 , It will be 1,000 times a standard earthquake .
Sure. what is it that you have to do with statistics
