Answer:
-28
Step-by-step explanation:
I believe is kilometers to millimeters
Given expression:
To simplify the expression as a fraction in simplest form, let us multiply both terms by 10. Then, both terms must also be divided by 10.
![\implies \dfrac{[10(0.8) - 10(0.6)]}{10}](https://tex.z-dn.net/?f=%5Cimplies%20%5Cdfrac%7B%5B10%280.8%29%20-%2010%280.6%29%5D%7D%7B10%7D)
![\implies \dfrac{[8 - 6]}{10}](https://tex.z-dn.net/?f=%5Cimplies%20%5Cdfrac%7B%5B8%20-%206%5D%7D%7B10%7D)
![\implies \dfrac{[2]}{10} = \dfrac{2}{10}](https://tex.z-dn.net/?f=%5Cimplies%20%5Cdfrac%7B%5B2%5D%7D%7B10%7D%20%3D%20%5Cdfrac%7B2%7D%7B10%7D)
When 2/10 is simplified in lowest terms, we get;
![\implies \dfrac{2}{10} \implies \dfrac{1 \times 2}{5 \times 2} \implies \dfrac{1}{5}](https://tex.z-dn.net/?f=%5Cimplies%20%5Cdfrac%7B2%7D%7B10%7D%20%5Cimplies%20%5Cdfrac%7B1%20%5Ctimes%202%7D%7B5%20%5Ctimes%202%7D%20%5Cimplies%20%5Cdfrac%7B1%7D%7B5%7D)
Therefore, 0.8 - 0.6 in fraction form is 1/5.
Answer:
answers below
Step-by-step explanation:
1. 21.50n (Print it)
2. 70+18n (Top Print)
3. This one is more complicated. First, you find out the cost from each store, by inserting 30 in place of n. (1. =645), (2.=610). Then, you subtract 610 from 645, which gets your difference to 35$.
4. There is an error in the wording, but the answer should be something along the lines of this. "Bill would need to buy 2 fewer shirts from Print It than from Top Print for Print it to be cheaper."
