2x−1/4y=1 solve for y please

EASY DUBS:

Step-by-step explanation:

2*x-((1/4)*y) = 1 // - 1

2*x-((1/4)*y)-1 = 0

2*x+(-1/4)*y-1 = 0

2*x-1/4*y-1 = 0 // + -1/4*y-1

2*x = -(-1/4*y-1) // : 2

x = (-(-1/4*y-1))/2

x = (1-(-1/4*y))/2

x = (1-(-1/4*y))/2

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
