B. x = 3y + 5
4x - 2y = - 10

x = 3y + 51

4x - 2y = - 10...,..2

substituting value of x in equation 2

4(3y+5)-2y=-10

12y+20-2y=-10

10y=-10-20

y=-30/10=-3 is answer

substituting value of y in equation 1

x=3×-3+5=-9+5=-4 is answer

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
