Answer:
You start at -9
-Open circle
-shade towards the right (where all the positive numbers are)
Open circle - ones that don't have a greater than or equal to. If it does then it's a closed one.
Shade towards the right cause y is less than 9
Answer:she spent 10 hours working in her aunt's store last week.
Step-by-step explanation:
Let x represent the number of hours that Lee spent working at the movie theater.
Let y represent the number of hours that Lee spent working at her aunt's store.
Lee worked a total of 30 hours at the movie theater and her aunt's store. This means that
x + y = 30
Her combined pay from the jobs was $240. She earned $9 per hour working at the movie theater and $6 per hour working in her aunt's store. This means that
9x + 6y = 240 - - - - - - - - - -1
Substituting x = 30 - y into equation 1, it becomes
9(30 - y) + 6y = 240
270 - 9y + 6y = 240
- 9y + 6y = 240 - 270
- 3y = - 30
y = - 30/ - 3 = 10 hours
The angles in a triangle must add up to equal 180. When it gives you angle A and angle B, you add them, then subtract it from 180, which will give you the angle C.
65 + 15 = 80
180 - 80 = 100 = Angle C.
It says to list them from smallest to greatest.
<B = 15, <A = 65, <C = 100
1.98
hope this helps have a nice day and i would appreciate if you mark me brainlest
