The equation we use here is:
(0.85)x +(1.00)y = (0.94)(x + y)
x is for the number of games he played on first day, y is the games on second day. The coefficients are the decimal form of percentages.

Simplify:
0.85x + y = 0.94x + 0.94y \\ \\ 0.06y = 0.09x \\ \\ \frac{6y}{100} = \frac{9x}{100} \\ \\ 6y = 9x \\ \\ 2y = 3x

To find x we need to use the ratio. We have 85/100 as the first day's ratio and because the games needs to be whole, we can simplify this as 17/20. So in first day, he played at least 20 games and won 17 of them.

When we plug the 20 into the equation as x:
2y = 3 \times 20 \\ \\ 2y = 60 \\ \\ y = 30
So he needs to play at least 30 games in order to get his score to 94%.

If (x)=3x-1 and s(x)=2x+1, which expression is equivalent to r over s (6) ?
katrin [286]

Answer:

\large\boxed{\dfrac{3(6)-1}{2(6)+1}}

Step-by-step explanation:

\left(\dfrac{f}{g}\right)(x)=\dfrac{f(x)}{g(x)}\\\\\text{We have}\\\\f(x)=3x-1,\ g(x)=2x+1\\\\\left(\dfrac{f}{g}\right)(x)=\dfrac{3x-1}{2x+1}\\\\\left(\dfrac{f}{g}\right)(6)\to\text{put x = 6 to the equation of the function}\ \left(\dfrac{f}{g}\right)(x):\\\\\left(\dfrac{f}{g}\right)(6)=\dfrac{3(6)-1}{2(6)+1}
