Step-by-step explanation:
2a -5a +8a.
2a +8a -5a
10a -5a = 5a
14-7=7
<em>Answer=5a+7</em>
The given equation is in point-slope form.
The general form of an equation in point slope form is:

Here m is the slope and

and

are the coordinates of the point.
So in given equation the slope is 2/3, and the coordinates of point are (1,3)
Answer:
77°F
Step-by-step explanation:
C = 5/9 (F - 32)
25 = 5/9 (F - 32)
-----------------------
5/9
45 = F - 32
+32 +32
------------------
77=F
