4,927 would be the correct answer you just do it on calculator
Answer:This is a tricky question that Reina and Sam are multiplying (84)5 (73)9 and their work are (84)5 (73)9 = 84 + 573 + 9 = 89712 Reina's (84)5 (73)9 = 84-573-9 = 820727 Sam's Actually they are doing or multiplying using exponents. Reina's work (8*)s(7³)º=8*+5+ 73+9= 8° 712 This is incorrect because she added exponents instead of multiplying exponents Sams work (8*)5 (7³)º=84x5 73x9= 820 727 This is correct because Sam multiplied exponents correctly Exponents are multiplied not added.
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
X= 135 and Y = 15. Hope that helps!
