To solve for x, subtract 3 from both sides, yielding x = 5. This demonstrates basic algebraic manipulation.

The subject of a sentence is the main noun performing the action. Here, 'sun' is the subject because it is doing the rising.

Water boils at 100°C under standard atmospheric conditions at sea level. This is a basic scientific fact.

The legislative branch, comprised primarily of Congress, is responsible for drafting and enacting laws. This is a fundamental concept in civics.

Egypt is predominantly located in Africa, though its Sinai Peninsula is part of Asia. This is a basic geographical fact.

Subtract 2 from both sides to get 3x = 15, and then divide by 3 to yield x = 5. This problem reinforces basic linear equation solving.

The perimeter of a rectangle is calculated as 2*(length + width). Substituting the values gives 2*(8+3) = 22 units.

Since the ratio is 3:4, for every 3 apples there are 4 oranges. With 12 apples, there are 12/3 = 4 groups, resulting in 4 x 4 = 16 oranges.

Plants use photosynthesis to convert sunlight into chemical energy. This process is essential for plant growth and energy production.

Weather refers to short-term atmospheric conditions, whereas climate denotes the long-term patterns and averages of weather over time. This distinction is fundamental in Earth sciences.
