A mother is five times as old as her daughter. In 6 years, the mother will be three times as old as her daughter. How old is she now?

Step-by-step explanation:

m = 5d

m-6+d-6 = 60 substitute for m:

5d-6+d-6 = 60

6d-12 = 60

6d = 72

d = 12 The daughter is 12 and the mother is 5(12) = 60

hope this helps

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
