Answer:

5.6

Step-by-step explanation:

We will let x= time babysitting

y= time hostessing

8.75x+10y=165

We know that x+6=y

So we have

8.75x+10(x+6)=165

18.75x+60=165

18.75x=105

x=5.6

Write the standard form of the equation of the line that passes through point at (4,2) and is parallel to whose equation is y=2x

solong [7]

Since the equation is parallel to y=2x-4 that means they have the same slope. Now that you have the slope and fortunately a point, you can solve this by using point slope formula
$y - y1 = m(x - x1)$
Which is what I did on the attached picture and just rearrange it after solving to Ax+By=C/2x-y=6
