Answer 6

In a scale drawing, a 42-foot tree is drawn 6 inches high. The flag pole
next to it is drawn 7-inches high. How tall is the actual flag pole?

Answer 7

Tank is already 1/12 full. Then enough gas is added to make it 2/3. Let " enough gas be X.
So 1/12 + X = 2/3
Subtract 1/12 from both sides
1/12-1/12 + X = 2/3 - 1/12
X = 7/12..... Was added to 1/12 to get 2/3
