1/3 = 4/12
1/4 = 3/12
7/12 they ate
12-7=5
5/12 is left
126/7=18 (so that's 18 ounces per bag)
now subtract the 3 ounces that were added to each bag:
18-3=15
so the old almond bag weighed 15 ounces
You need to put the 15 over 1 and multiply 6 by 3 to get 18, which would be added to 2 to get 20/3, which you flip in order to get 3/20. You multiply the 15 by the 3 and the 1 by the 20 to get 45/20. You then simplify to get 2 1/4
You must subtract, add, then divide. The answer is 3.66666666667
Answer:
(-infinity, 1) ∪ (1,3) ∪ (3, +infinity)
Step-by-step explanation:
Here only the 2nd function, g(x) = x^2 - 4x + 3, affects the domain. Recognizing that division by zero is undefined, we set g(x) = 0 anyway and solve for x: x^2 - 4x + 3 = 0 = (x -3 )(x - 1) = 0. Thus, x cannot have either value 3 or 1. Using this info, we write the domain as follows:
(-infinity, 1) ∪ (1,3) ∪ (3, +infinity). This is Answer #3.
