Triangular Tables A classroom has triangular tables. There is enough space at each side of a table to seat one child. The
tables in the class are arranged in a row.
1. How many children can sit around 1 table? Around a row of two tables? Around a row of three
tables? Explain
2. Find an algebraic expression that describes the number of children that can sit around a row of n
tables. Explain in words how you found your expression
3. If you could make a row of 125 tables, how many children would be able to sit around it?
4. If there are 26 children in the class, how many tables will the teacher need to seat all the children
around a row of tables? Explain your answer and how you derived at your answer.​

We are told to solve for n given the equation 3(n + 4) = -6 + 15n. We can solve for n by first using the distributive property, which gives us 3n + 12 = -6 + 15n. Now, subtract 15n from both sides, giving us -12n + 12 = -6. Next, subtract 12 from both sides to get -12n = -18. Now, divide both sides by -12 to get n = 18/12, or 3/2 when simplified. Therefore, the value of n in the equation 3(n + 4) = -6 + 15n is 3/2. Hope this helped!
