75 + 30n, n = 53 my answer is 1,1665 am I right?

Right!

Thanks!

To find the value of the expression 75 + 30n when n = 53, you need to substitute the value of n into the expression and perform the calculation.

Substituting n = 53 into the expression, we have:
75 + 30(53)

Now, we can multiply 30 by 53:
75 + 30 * 53 = 75 + 1590

Next, we can add the two numbers:
75 + 1590 = 1665

So, the correct answer is 1665.

Therefore, your answer of 11665 is incorrect. The correct answer is 1665.
