What is the slope of the line?<br><br> 3(y-1)=2x+2
Aleks [24]

Answer: 2/3

Step-by-step explanation:

3(y-1) = 2x + 2

Expand: 3y - 3 = 2x +  2

Isolate the y by adding 3 to both sides: 3y = 2x +5

Isolate the y by dividing 3 from both sides: y = 2/3x +5/3

Remember, in y = mx + b, m = slope.

So, 2/3 is the slope.

22. Find the perimeter of the square:<br> 28
sergejj [24]

Answer:

  56√2 ≈ 79.20

Step-by-step explanation:

The hypotenuse of an isosceles right triangle is √2 times the side length, so the side length here is ...

  s·√2 = 28

  s = 28/√2

The perimeter is 4 times the side length, so is ...

  P = 4s = 4·28/√2

  = 4·28·(√2)/2 . . . . . multiply by (√2)/(√2) to rationalize the denominator

  = 56√2 ≈ 79.195959

The perimeter of the square is 56√2, about 79.20 units.

If Lebron can run 12 laps in 2 hours, approximately how long will it take him to run 60 laps?
ddd [48]

Answer:

10 hours

Step-by-step explanation:

Let's set up a proportion using the following setup.

hours/laps=hours/laps

We know that it takes him 2 hours to run 12 laps. We don't know how long it will take him to run 60 laps, so we can say it takes x hours to run 60 laps.

2 hours/12 laps=x hours/60 laps

2/12=x/60

We want to find out what x is. In order to do this, we have to get x by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.

x is being divided by 60. The opposite of division is multiplication, so multiply both sides by 60.

60*2/12=x/60*60

60*2/12=x

10=x

It will take Lebron 10 hours to run 60 laps.
