A={2,4,6,8,10} and b={1,2,3,4,5}
which solution set is the union a u b?
a. {2,4}
b.{1,2,3,4,5,6,8,10}
c.{1,3,5}
d.{7,9}

the correct answer is A

Step-by-step explanation:

y = x + 95

y = 42 + 95

y=137 mm hg

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.
