Step-by-step explanation:
<u>Step 1: Define</u>
-6(t + 2) = 18
<u>Step 2: Solve for </u><em><u>t</u></em>
- [Distributive Property] Distribute -6: -6t - 12 = 18
- [Addition Property of Equality] Add 12 on both sides: -6t = 30
- [Division Property of Equality] Divide -6 on both sides: t = -5
I think the best property to use is electronegativity since that is how much it attracts/wants electrons. The larger the difference in electronegativity is between two atoms, the stronger the ionic bond will be. This is also why two atoms need to have a minimum difference between the electronegativity to be considered ionic and not covalent.
To find the price after the discount the equation would be 39..98x.30which would equal 11.99. subtract that from the price before the discount and you get $27.99. thats your first answer. to find the second answer you would do 23.99 divided by 11.99 (the diacount from the first equation) to get the discount rate of 2% so your final answers are $27.99 and 2%
