Use the distributive property to rewrite the expression as a multiple of a sum of two numbers with no common factor.

you need to use distributive property which the steps are Multiply, or distribute, the outer term to the inner terms.Combine like terms.Arrange terms so constants and variables are on opposite sides of the equals sign.

Step-by-step explanation:

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.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
