I got 5 inches b/c 8-5 1/4 equals to 2 3/4. 2 3/4 is equal to two feet and 9 inches. 28 inches is equal to two feet and four inches. Nine inches minus four inches equals five inches.
Answer:
it would take 65 hours to produce all of the order.
Step-by-step explanation:
1. you already would figure out that 26 hours=4 cases or 6.5 hours per case of hairbrushes.
2. You would figure out that 26+26 is 52 so 52 hours for 8 cases
3. Then you remember u have 8 cases of hairbrushes now. Set up a mental equation where you can solve in your mind: if I need 10 cases, but have figured out I only calculated 8, how much more would I still need to meet the order?
4. After mentally solving the hypothetical problem, you then would conclude you needed 2 more cases from 8 to equal 10.
5. you then divide 26 hours per 4 cases and you get 13 hours for 2 cases.
6. finally you multiply 26+26+13 which you would get 65 as the answer
Answer: (9+10x)(9-10x). Explanation: To factor this, look for numbers that can be FOILed (first, outer, inner, last). You know what if you separate the equation into two different parenthesis, one has to be negative and the other positive because there are no x^1 variables. 81 is equal to 9*9, and 100x^2 is equal to 10x*10x. Split these into two parenthesis, and add corresponding negatives. The answer should be (9+10x)(9-10x).
