Demostrar que los puntos A(-3,3), B(-1,-1) y C (1,-5) son colineales:

AB= 4.47, BC= 4.47 Y AC= 8.94

AB= 5.66, BC= 5.66 Y AC= 11.32

AB=6, BC= 6 Y AC= 12

AB= 5.66, BC= 4.47 Y AC= 10.13

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
