Answer:
Since angle d, a, and e are supplementary, d+a+e =180 degrees.
Given that line LK and BC are parallel
By the alternate interior angle theorem, e=c and d=b.
Substitute:
d+a+e=b+a+c=180
Since b+a+c is the sum of the angles of triangle ABC, the sum of the interior angle of triangle ABC (which could be any triangle of any size and shape) is 180 degrees.
The function d(t) represents the distance traveled by the train after t hours. d(5) is the total distance traveled by the train after 5 hours, which means 6:00 pm. The d(2) is the total distance traveled by the train after two hours, 3:00 pm. The expression d(5) - d(2) represents the total distance traveled by the train from 3:00 pm to 6:00 pm or for traveling at a constant speed for 3 hours.
Answer:
Step-by-step explanation:
8(v−4)+7v=−2
(8)(v)+(8)(−4)+7v=−2
8v+−32+7v=−2
(8v+7v)+(−32)=−2
15v+−32=−2
15v−32=−2
Add 32 to both sides.
15v−32+32=−2+32
15v=30
Divide both sides by 15.
15v/15=30/15
v = 2
If you break it up it would be 19
Just add them all as single single numbers, Not double digit ones.
Like this, 3+3+4+9 = 19
Hope that helps, Good luck! (:
