The product of a number, k, and seven is three more than the quotient of the number and three-fifths.
Write an equation to represent this situation.
7k - 3 = k / (3/5) simplify
7k - 3 = (5/3)k
The flag that inspired the national anthem was a rectangle 30 ft wide and 42 feet long. Pieces of the flag have been lost. It is now 30ft wide and 34 ft long. How many square feet have been lost?
Original area = 30 x 42 = 1260 square feet
New Area = 30 x 34 = 1020 square feet
1260 - 1020 = 240 square feet have been lost
