Answer:
x = 9°
y = 26°
Step-by-step explanation:
4x + 6x = 90

D is the function that is graphed
Answer:
First one is the correct answer!!
Step-by-step explanation:
Answer:
x=5, y=8. (5, 8).
Step-by-step explanation:
3x+5y=55
5x+4y=57
---------------
5(3x+5y)=5(55)
-3(5x+4y)=-3(57)
-------------------------
15x+25y=275
-15x-12y=-171
---------------------
13y=104
y=104/13
y=8
3x+5(8)=55
3x+40=55
3x=55-40
3x=15
x=15/3
x=5
