Answer:
Step-by-step explanation:
Given
Lines x and y
Transversal b
Required
Find 
From the attachment, 
and 
are vertically opposite.
This means that
Similarly
and are supplementary angles
So:
Make 
the subject
The relationship between and is that they are supplementary angles because:
Plug in -2 for a, 3 for b, and -5 for c. Then it'd be | (-3)^2 - 2(-2)(-5) +5 (3) |. Then, multiply everything to get | 9 -20 +15 |. Then, add/subtract to get | 4 |. Finally, take the absolute value and get 4.
You need to add 1 and 5 and get 6
do 150 divided by 6
you get 25
Answer: b & c
Step-by-step explanation:
first i found how many hours tonya works in one week which was 20. i got that by dividing 60 by 3. then that set me up for finding the answer to the other problems as well. 60+20=80 so a wouldn’t have worked. 5x5 is 25 and she only worked 20 hours a week. and she would’ve worked 320 hours in 16 weeks, not 240. hope this helps!! :)
