The diagram shows a plan for a piece of mobile. A chain will hang from the centroid of the triangle. At what coordinates should the artist attach the chain?

The two expressions gives a different value because 0 is insignificant during subtraction but significant in division

Subtraction and Division

Note that taking the difference of a value and zero will return the original value since 0, in this case is insignificant.

For the ratio, the ratio of 0 and any constant will return zero. Hence;

• 10 - 0 = 10 (retirns the value of 10)
• 0/10 = 0 Returns the numerator

The two expressions give a different value because 0 is insignificant during subtraction but significant in division

Answer:

Inverse operations are opposite operations that undo each other. Addition and subtraction are inverse operations. Multiplication and division are inverse operations.

Step-by-step explanation:

Final answer:

Inverse operations are mathematical operations that undo each other. Addition and subtraction are inverse operations, as are multiplication and division. They're used in solving equations or simplifying expressions.

Explanation:

Inverse operations are operations that undo each other. These are used primarily in solving equations or simplifying expressions in math. The principal of inverse operation is that it cancels out the operation of the other, getting you closer to finding the exact numeral you're looking for.

Regarding the four basic mathematical operations, addition and subtraction are inverse operations of each other, and multiplication and division are inverse operations of each other. This means:

• The inverse operation of addition is subtraction. If you add a number and then subtract the same number, you return to your original number. For example, for the numbers 5 and 3, if you perform the operation 5 + 3 - 3, you return to 5.
• Similarly, the inverse operation of subtraction is addition. For the numbers 5 and 3, if you perform the operation 5 - 3 + 3, you return to 5.
• The inverse operation of multiplication is division. If you multiply a number by another number and then divide by the same number, you return to your original number. For example, for the numbers 5 and 3, if you perform the operation 5 * 3 / 3, you return to 5.
• And, the inverse operation of division is multiplication. For the numbers 5 and 3, if you perform the operation 5 / 3 * 3, you return to 5 (rounding to the nearest whole number).
