Question

what is a certain of a number increased by 4

Answer 1

Answer:

n+4

Step-by-step explanation:

Any time you need to change a word problem involving a variable and you are not sure how to do it, ask yourself how would I tackle this problem with a known number and then trace what operation was used.

If I asked you what is the result if the number 7 is increased by 4, you would likely say 11. Tracing your work, you realize that you added 7 + 4 = 11.

Thus a number (e.g. n) increased by 4 is simply:

n + 4
