mr_godi [17]

Remember PEMDAS (Parentheses, Exponents, Multiplication ⇔ Division, Addition ⇔ Subtraction), which is the order you solve parts of an expression.

(7 + 5) ÷ 6 + 10² Add 7 and 5 (Parentheses)
12 ÷ 6 + 10² Square 10 (10 x 10) (Exponents)
12 ÷ 6 + 100 Divide 12 by 6 (Division)
2 + 100 Add (Addition)
102

Andre is setting up rectangle tables for a party. He can fit 6 chairs around a single table. Andre lined up 10 tables end to end

IRINA_888 [86]

If there is one table (t=1) then 6 chairs (c=6) can be placed around the table, 2 along the length on each side and 1 at each end.
When t=2, and the tables are end to end (joined at their width) c=10, that is, 4 chairs on each side of the double table and 1 at each end. Each time a table is added c increases by 4 so we can write c=4t+2 the constant 2 being the single chair at each end. If the tables are separated then c=6t.
