Why do you first combine like terms and then use the distributive property to solve 8(5x+9x+6)=160

You are following PEMDAS:  (this is the order you use to solve a problem)

Parentheses, Exponents, Multiplication, Division, Addition, Subtraction


So you first simplify inside the parentheses, then you distribute/multiply 8 into the simplified values in the parentheses.


Also it would be easier to work with if you combined the like terms/simplified, because you still have to add them anyways if you didn't combine them earlier

Fun park charges an entry fee of $2 for any family with less than 5 members. The park charges $3 less than the number of family
RideAnS [48]

A piecewise function is a function that behaves differently in different intervals.

Here the piecewise function is:

f(x) = $2     if    x < 5  

f(x) = x - $3  if   x ≥ 5

We know that:

"Fun park charges an entry fee of $2 for any family with less than 5 members."

"The park charges $3 less than the number of family members for the entry of any family with 5 or more members."

If we define x as the number of members of a family, the function of the price will be:

f(x) = $2     if    x < 5 (the cost is $2 if the family has less than members)

f(x) = x - $3  if   x ≥ 5   (the cost if the family has 5 members or more)
