Which algebraic expression represents "the difference of fifty-four and seven times a number"? 54 minus 7 n StartFraction 54 Over 7 n EndFraction 7 minus 54 n 54 + 7 n

Answer: 54-7n

Step-by-step explanation:

When we talk about mathematical language, the difference between two numbers, quantities or terms is the substraction operation.

For example, the difference between a and b is:

a-b

On the other hand, if we read a numer c times a number n, this means both numbers are multiplied.

For example:

c times n is:

(c) (n)

So, according to the explained above, "the difference of fifty-four and seven times a number n" is:

54-7n
