The teachers had to transport 166 students by bus on a field trip. each bus holds 65 students. how many buses do they need to order so no one is left behind?

In order for no one to be left behind you would need 3 buses because you cant have 2.5 buses.
Hope that answers your question

The answer would be 16

(6,1)(5,4)slope = (4 - 1) / (5 - 6) = 3/-1 = -3y = mx + bslope(m) = -3use either of ur , = 6 and y = 1now sub and find b, the y int1 = -3(6) + b1 = -18 + b1 + 18 = b19 = bso ur equation is : y = -3x + we need it in standard formy = -3x + 3x to both sides3x + y = 19 < == standard form
