To calculate the number of correct answers you got on a test, you can use the formula: (score / total possible score) x total number of questions. In this case, you got a score of 78 on a 65-question test. So, (78 / 100) x 65 = 50.7. Therefore, you got approximately 51 questions correct on the test.
you use a system of equations to eliminate a variable. the eggs were 80 cents and the bread was 1.75$.
65% of 18= 65% * 18= 0.65 * 18= 11.7
False. 65 equals 10 plus 65 65 = 10 + 65 65 = 75 You know that this is false because 65 doesn't equal 75.
