This is an example of the Associative Property of addition.
On a test with 42 questions, answering 37 correctly yields a score of approximately 88 percent. This result is obtained by dividing the number of correctly answered questions by the total number of questions, and then multiplying that result by 100 to find the percent.
The subject for this problem is percentages, a common topic in mathematics. To solve this, you need to relate the number of correct answers to the total number of questions. The formula for percent is (part / total) * 100, where the part is the number of problems you answered correctly (37), and total is the overall number of questions on the test (42).
In this case, you'd calculate (37 / 42) * 100, which equals approximately 88.09%. Therefore, if you answered correctly on 37 out of 42 questions, your score would be about 88 percent.

Distributive property: a(b + c) = ab + ac
4n - 2 - 2n = 2(2n - 1 - n)
4n - 2 - 2n = 2n - 2 = 2(n - 1)
