Angle x is (2n+12) and angle y is 3n+18 find the measure of angle x

I have a solution.

Step-by-step explanation:

(2n+12) and 3n+18

=2n+12=3n+18

=2n+3n=12+18

=5n=30

=n=30÷5

=n=6

therefore,x=n=6

there is no

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.
