Rosita can wax her car in 2 hours or 120 minutes. When she works together with Helga, they can wax the car in 45 minutes. How lo

Mashcka [7]

<h2>Time taken by Helga to wax the car is 72 minutes</h2>

Step-by-step explanation:

Let w be the work of waxing.

Rosita can wax her car in 2 hours or 120 minutes.

Time taken by Rosita = 120 minutes

$\texttt{Rate of Rosita = }\frac{W}{120}$

Let time taken by Helga be t,

$\texttt{Rate of Helga = }\frac{W}{t}$

When she works together with Helga, they can wax the car in 45 minutes.

We have

$\frac{W}{\frac{W}{120}+\frac{W}{t}}=45\\\\120t=45(120+t)\\\\120t=5400+45t\\\\t=72minutes$

Time taken by Helga to wax the car is 72 minutes

I need help, I don’t need an explanation, just the answer

meriva

Answer:

$x = 48 \: \: \: \: \: \: y = 16$

Step-by-step explanation:

$y = - x + 4y$

$y + x = 4y$

$y + x - 4y = 0$

$- 3y + x = 0$

$- x + 4y = 16$

$- 3y + x = 0$

$- 3y = - x$

$y = - \frac{1}{3} ( - 1)x$

$y = \frac{1}{3} x$

$4 \times ( \frac{1}{3} )x - x = 16$

$\frac{1}{3}x = 16$

$x = 48$

$y = \frac{1}{3} \times 48$

$y = 16$

Hope this is correct and helpful

HAVE A GOOD DAY!
