Hi Hailey!

2(x + 3) = 3(x - 3)

Explanation:
> Twice translated to mathematical terms is x 2. 

> Sum is the result of the operation addition.

> Variables stand for an unnamed or unknown number(s). 'A number' indicates that we don't know what number it is exactly, therefore it'll be represented as a variable. 

> Equal to indicates the equality sign, thus making this an equation.

> Three times = x 3

> Difference is the result of the operation subtraction.

>  Multiplication goes before addition and subtraction in the PEMDAS rule, however parenthesis comes before multiplication. The x + 3 and x - 3 are in parentheses because we need the sum and difference between x and 3 first before multiplying it.

At a school fair 70% of the people are under 16 years old. One third of the people remaining are teachers. If there are 21 teach
Tamiku [17]
In the fairest school 70% are below 16 years old 1/3 are teachers which is equals to = 21 Let’s start solving: => 1/3 of 100% => 100 / 3 = 33.33% thus 33.33% = 21 => 21 x 3 = 63, is the total number of people in the school. Let’s try solving the number of people below 16 years old Have you notice that you are asking for a 70% of students but there are already 33.33% of teacher. Thus your given problem is not right already. => 100% - 33.33% = 66.67% that’s the only remaining percentage and not 70% => 63 * .6667 = 42.0021 Thus, there are around 42 people who are 16 years old younger.
