We are giiven with two realms: 36 students who passed test 1 and <span>38 who passed test 2 in which 42 students overall took the test. to determine U' or those who didn't pass either of the tests, then we use the formula: A or B = (A+B)-AandB A/B = (36+38)-AandB= 74-AandB 42 = A+ B - AandB + U'; 42 = 74- AandB+ U'
where U' is the number who did not pass
U'= -32 + AandB U' cannot be negative but can be zero, AandB = 32 @ minimum number of those who fail. AandB cannot be greater than 38 but can be greater than 36, hence U' = -32 + 38 @ maximum number of those who fail.
First combine like terms (-9n-3n=-12n) Then, subtract 6n on both sides (to get rid of the 6n) = -18n Then, add 8 to both sides (does not matter) = 0 Finally divide (answer is 0)
A very small dinosaur , the microraptor was only 1.3 feet long. one of the largest dinosaures the diplodocus was about 91 feet long. how many times as long as the microraptor was the diplodocus ? =78 feet
