As the amount is $100 dollars, you will have to find what 35% of this is. The best way to do this is to divide both 100 and 35 by ten, giving you ten and 3.5. AS 10 is 10% of 100, you should then multiply then, by three and half, therefore, giving you 35- meaning the discount is $35 dollars. Hope this helps
B) 14.
If you start with subtracting the 8 pages from 50, you get 42 remaining pages. Then it says 2/3 of the REMAINING pages so you divide 42 into thirds. 42/3=14. You want 2/3 of that, so you multiply the 14 by two to get 28 (it's like there are three piles of 14 pages and you want only 2 out of the three piles). So now you've used 28 pages + the original 8. You've used a TOTAL of 36 pages. Subtract 36 from 50 and you get 14 left.
Answer:
(-2, 6)
Step-by-step explanation:
we have
----> equation A
----> equation B
equate equation A and equation B
The formula to solve a quadratic equation of the form
is equal to
