R / (r + g) = 1/5 === 5r = r + g === 4r = g
<span>(r + 5) / (r + 5 + g) = 1/3 --- 3r + 15 = r + 5 + g </span>
<span>2r = g - 10 ... 4r = 2g - 20 </span>
<span>g = 2g - 20 </span>
<span>g = 20 .... 4r = g ... r = 5 </span>
<span>20 green and 5 red </span>
Answer:
f(x) = 3x+2
g(x) = 2x - 2
To find (f-g)(x)
(f-g)(x) = f(x) - g(x)
Substitute f(x) to 3x+2 and g(x) to 2x -2
(f-g)(x) = (3x+2) - (2x-2)
Open the brackets
(f-g)(x) = 3x+2-2x+2
Rearrange
(f-g)(x) = 3x-2x+2+2
(f-g)(x) = x + 4
Answer is option A = x + 4
