Time is the duration during which any activity or work is performed. Jeanette's sister started 4 hours before the 9:00 pm which is 5:00 pm.
Given-
Jeanette's sister charges $5.50 per hour before 9:00 pm.
Jeanette's sister charges $8 per hour after 9:00 pm.
She finished babysitting at 11:00 pm
She earned total money $38.
Time is the duration during which any activity or work is performed.
Total hour she worked after the 9:00 pm,
Thus she worked total 2 hours after the 9:00 pm. She charges charges $8 per hour after 9:00 pm.Hence money earned by her in 2 hours after 9:00 pm ,
Thus money earned by her in 2 hours after 9:00 pm is $16. The money earned by her before the 9:00 pm is addition of money earned by her before 9:00 pm and after 9:00 pm. Let money earned by her before 9:00 pm is $x. Thus,
Thus the money earned by her before 9:00 pm is $22.
She charges $5.50 per hour before 9:00 pm. Hence the $22 charged by her in hours,
Therefore, hence Jeanette's sister started 4 hours before the 9:00 pm which is 5:00 pm.

Hey there! :D Jeanette's sister started at 5:00 PM. To get that answer, here's what I did: From 5-9 PM, she earned $22. That's because 5.50 x 4 = 22, then from 10-11, she charged $8 which is 8 x 2 = 16 + 22 = $38. Again, she started at 5 PM.
Hope it Helps and makes sense! :D
B) 90 − (8a + 9) = (11 + 2a)
C) (11 + 2a) − 90 = (8a + 9)
D) (8a + 9) − (11 + 2a) = 90
Answer:
B
Step-by-step explanation:
Seeing the above angles we conclude that
(11+2a)+(8a+9)=90 (since they are complementary angles)
So
Subtracting (8a+9) to both sides we get
90-(8a+9)=11+2a
Answer:
The answer is B.) 90 - (8a + 9) = (11 + 2a)
Step-by-step explanation:
90 − (8a + 9) = (11 + 2a)
Complementary angles add to 90°
