Answer:
8
Step-by-step explanation:
8 is the digit after 7 and previous to 9
It is where the numerator and the denominator (or both) contain a fraction.
Percents is a number out of 100. So basically what you’re going to do here is add up the percents. 40+20+10. Add that up and you get 70. You then subtract 70 from 100. You get 30. So the percentage of red pens is 30%.
360 miles in 8 hours you do 135 divided by 3 which gives you 45 then you do 45 times 8 giving you 360 I hope I helped and I’m sorry if just didn’t give you the correct answer I tried.
R^2-7r-8=0
<span>=> ( r - 8) ( r + 1 ) = 0 </span>
<span>=> r - 8 = 0 or r + 1 = 0 </span>
<span>=> r = 8 , r = -1
the answer is A</span>
