To write the quotient of a number and 6 as an expression, you can represent the number as a variable, such as ( x ). The expression would then be written as ( \frac{x}{6} ). This indicates that the number ( x ) is being divided by 6.
To write the sum of a number k and 7, you would use the mathematical expression k + 7. This expression represents adding the value of k to 7. In algebraic terms, this is known as an addition operation where k is the addend and 7 is the other addend. The result of this addition operation would give you the sum of k and 7.
The expression is 9*x.
It means you should invent a short problem (story) where an addition has to be made.
A - B = A + (-B) A - B = A + (-B) A - B = A + (-B) A - B = A + (-B)
Oh, isn't that just lovely? To express the sum of a number and ten in mathematical terms, you simply write it as "x + 10" where 'x' represents the number you're adding ten to. Just imagine that number and ten dancing together on the canvas of mathematics, creating a beautiful harmony of addition. Happy little numbers!
