Question

Unit 4 Lesson 16 practice problems​

Answer 1

Compound units in mathematics are formed by combining two or more basic units. To add or subtract compound units, the units must be of the same type. Follow the steps of identifying the quantities, converting units if necessary, adding or subtracting the quantities, expressing the result, and rounding to the correct number of significant figures.

Step-by-step explanation:

In mathematics, compound units are units that are formed by combining two or more basic units. When adding or subtracting compound units, it's important to ensure that the units are compatible. This means that the units must be of the same type. For example, you can add or subtract distances in meters, but you cannot add or subtract distances in meters and kilograms.

To solve compound unit problems, follow these steps:

1. Identify the given quantities and their units.
2. Convert the quantities to the same unit if necessary.
3. Add or subtract the quantities to obtain the result.
4. Express the result in the appropriate unit.
5. Round the result to the correct number of significant figures.

Here's an example:

Adding 5 meters and 3 meters:

1. Identify the given quantities and their units: 5 meters and 3 meters.
2. The quantities are already in the same unit.
3. Add the quantities: 5 meters + 3 meters = 8 meters.
4. The result is 8 meters.
