Pie

Answer:

C) 145 degrees

Step-by-step explanation:

angles 2 and 5 are same side interior angles, which means they're supplementary. (they add together to make 180)

using that, you can make the following equation:

(x is angle 2 to avoid confusion)

35 + x = 180

<em>subtract 35 from both sides</em>

x = 180 - 35

x = 145

Aaron is at a spot in his book where the page numbers of the two facing pages have a product of 1980 what are the two page numbe
Alona [7]
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>

Two trains leave stations 456 miles apart at the same time and travel toward each other. One train travels at 105 miles per hour
love history [14]

Answer:

let x=distance 105 mph train traveled

(456-x)=distance 85 mph train traveled

Travel time = distance/speed (equal in both directions)

 

x/105=(456-x)/85

85x=105*456-105x

190x=105*456

x=105*456/190=252 miles

travel time=252/105=2.4 hrs

ans:

The two trains will meet in 2.4 hrs
