Answer:
She must score 90 points
Step-by-step explanation:
Find the average of the first 2 tests
76 + 80 = 156
Divide the sum of the first 2 tests by how many tests there were
156 ÷ 2 = 78
Multiply 82 by 3
82 x 3 = 246
Subtract 156 from 246
246 - 156 = 90
Add all the numbers together to get the average
90 + 80 + 76 = 246
246 ÷ 3 = 82

I can't tell you the answers cause that's cheating but I can explain how to do it.
Let's use number 1 for an example. It says 1/2 x 2 1/3. First what we want to do is turn all mixed numbers into fractions. So how to do that is take the whole number, in this case 2, and multiply it by the denominator, which in this case is 3. The answer you will get is 6. Then you have to add the numerator onto that, which means 6 + 1 = 7. So now the equation is 1/2 + 7/3. Now you can just multiply both numerators and denominators, so 1 x 7 and 2 x 3, and you will get 7/6, which can be converted to 1 1/6. Apply this method to any of those problems.
Hope this helped!
