One faucet fills up a bathtub in 15 minutes while the second fills it up in 10 minutes. If both faucets are turned on, what frac
yaroslaw [1]
Faucet one fills up \frac{1}{15} of the bathtub in one minute and faucet two fills up \frac{1}{10} of the bathtub in one minute. If both are one then they will fill up  \frac{1}{15}+ \frac{1}{10} =  \frac{5}{30} =  \frac{1}{6} So, 1/6 of the bathtub in one minute.

1) y = 2x – 17<br> -3x – y=-13
scoray [572]

Answer:

<h2>x = 6, y = -5 → (6, -5)</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}y=2x-17&\text{subtract}\ 2x\ \text{from both sides}\\-3x-y=-13\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}-2x+y=-17\\-3x-y=-13\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad-5x=-30\qquad\text{divide both sides by (-5)}\\.\qquad\boxed{x=6}\\\\\\\text{Substitute the value of x to the first equation}\\\\y=2(6)-17\\y=12-17\\\boxed{y=-5}
