\bf \textit{equation of a circle}\\\\ (x- h)^2+(y- k)^2= r^2 \qquad center~~(\stackrel{5}{ h},\stackrel{-2}{ k})\qquad \qquad radius=\stackrel{3}{ r}\\[1em] [x-5]^2+[y-(-2)]^2=3^2\implies (x-5)^2+(y+2)^2=9

Solve x - 5y = 6 for x.<br> Ox= -5y + 6<br> Ox= -5y - 6<br> Ox = 5y + 6<br> Ox = 5y - 6
valentina_108 [34]

Answer:

See below

Step-by-step explanation:

Solve x-5y=6 for x

First, we need to isolate the x by moving -5y to the other side.

To do this, we need to add 5y to both sides

x - 5y=  6

  +5y   +5y

x= 5y+6

So, your third answer is correct

Solving a word problem involving rates and time conversion
LUCKY_DIMON [66]

Answer:

It takes 4.75 hours to travel 247 miles.

Step-by-step explanation:

This question is solved by proportions, using a rule of three.

A car travels at an average speed of 52 miles per hour.

This means that in 1 hour, the car travels 52 miles. How many hours for it to travel 247 miles?

1 h - 52 m

x h - 247 m

Applying cross multiplication

52x = 247

x = \frac{247}{52}

x = 4.75

It takes 4.75 hours to travel 247 miles.
