Basically you know that they are 2 consecutive numbers whose product is 1980.
<span>n*(n+1)=1980 </span>
<span>n^2 + n - 1980 = 0 </span>
<span>(n -44)(n + 45)= 0 </span>
<span>n=44 </span>
<span>so the 2 page numbers is 44 and 45. </span>
<span>The faster way is just to take the square root of 1980 and since that is 44.497 you can conclude that the 2 numbers is below and above it (44, 45)</span>
Answer:
$9.45
Step-by-step explanation:
1. First, you want to figure out how much one text message costs. To do this, divide the dollar amount (28.20) by the number of text messages (188). You get 0.15, or $0.15 per text message.
2. Using this $0.15 per text message, you can calculate how much 63 text messages costs. You simply multiply $0.15 by 63 to get $9.45, which is your answer.
Hope this helps! :)

Answer:
The percent of time that was spent on reading is 12%
Step-by-step explanation:
To figure this question out, first add up all of the known percentages. So for this question, this would be: 11 + 28 + 22+ 15 + 12, or 88. The total of all the percentages must be equal to 100%. So, subtract the sum of all the known percentages from 100.
100 - 88 = 12%
Hope this helps! ^-^
