Midpoint of (-7,-14) and (-13,-6)

(-10,  -4)

Step-by-step explanation:

(-13-7/2, 6-14/2)

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.

109 is the nearest whole number/final answer! : )
