Answer:
1. a= 7, A = 49 degrees
Side A = 7 , Side B = 24, Side C = 25
A= 49 degrees, C = 90 degrees , B=41
2. A= 4, B = 6.9, C=8
A= 22 degrees, B = 68, C= 90
3. A= 7, B = 14.4, C=16
A= 45 , B=45 , C=90
A fraction and decimal because it equals 1 30/100 or 1 .03.
The answer is quite obvious if you look carefully between 4-7 hrs. If you look carefully, the most hours studied is between 4-7 hrs and it’s mostly descriptive there so D is your answer I think-
Answer:
(-1, 3)
Step-by-step explanation:
Add the two equations together:
(7x - 2y) + (2y - 5x) = -13 + 11
Simplify:
2x = -2
x = -1
Plug x=-1 into the first equation:
7(-1) - 2y = -13
-7 - 2y = -13
-2y = -6
y = 3
