This is purely guesswork, but I interpret this question to mean, "Does 15(89 - 74) = 15 x 89 - 15 x 74?" The answer is yes. If that was not the intent of the question, please re-submit with the operations written out. Answers.com doesn't do plus signs.
If you mean: 5*(2x-3)+89 then it works out as 10x+74
12p-15+8-4p = 89 12p-4p = 89+15-8 8p = 96 p = 12
13.35
$89.00 - 15% = $75.65
94
89-15 = 74
15 + 74 = 89.
68
If you mean: 5*(2x-3)+89 then it works out as 10x+74
15 - (-89) = 104
80%
18 times 5 equals 90.
89 pounds minus 15% = 85% of 89 pounds = 89*85/100 pounds = 75.65 pounds
89
12p-15+8-4p = 89 12p-4p = 89+15-8 8p = 96 p = 12
Assuming all questions are worth the same amount of points, the answer is you can miss 23.14 problems, or rounded, 23 problems, which makes more sense.Here is the work, it's fairly elementary, so I won't explain each step:Let n be the number of problems you can miss.(89-n) / 89 = 74 / 100
13.35
