Well so far, Kate has saw 65% of her workout
65% of total = 26
0.65 * t = 26
t = 26/0.65
t = 40 laps
See its a straight line and the angle of straight line is 180
so according to this
7x+x-4 = 180
8x = 184
x= 23
therefore angle DBC 23-4 = 19
SO 19 IS THE ANSWER
Expression: (x + 4)/3
Plug in 5 for x
(5 + 4)/ 3 = 9/3 = 3
The solution is 3
I think the answer might be "c"
