the students and adults will be taking buses to six flags, if each bur can hold 40 people homy buses are needed

4

Step-by-step explanation:

135÷40=3.375

The slope of the line that is perpendicular to the line whose equation is 2x + y = 4 is 1/2; solution: the equation 2x + y = 4; it can be written as y =4-2x; y = -2x+4; this equation is in the form of y = mx + c; where m is the slope of [ the line. thus m = -2; the slope of the line perpendicular to the above line is m*m1 = -1; -2*m1 = -1; m1 = 1/2; ] 
hope this !
