Answer:
x= -11;y= -19
Step-by-step explanation:
lets name y-2x=3 "A" ;
name 3x-2y=5 "B".
2A: 2y-4x=6
2A+B: (2y-4x)+(3x-2y)=6+5
2y-4x+3x-2y=11
-x=11
so x= -11
so A is : y-2 (-11)=3
y+22=3
so
y= -19
4: 1 because you could divide both sides of the ratio by 25

Answer:
-1
Step-by-step explanation:
Cos (x) = adj/hyp
cos (x) = 13/25
x = cos⁻¹(13/25)
