X=7y-8 because subtract 7y from both sides and then multiply by 1
Let us pretend x is the number.
The equation will be 13-6x=11+4x.
Solve.......
X=2/10
In degrees: 3π/4 radians = 135°
Angle of x=135° is in the 2nd Quadrant and has negative cos x values and positive sin x values.
cos 135° = cos ( 90° + 45°)= - sin 45° =

sin 135° = sin ( 90° + 45° ) = cos 45° =

A) an answer that cannot be written as a fraction.
Answer:
so I think its 138 bowls so ya cause 6 times 23 is 138
