2 answers:

8 0

The common denominator of 2/3 and 10/15 is 15.
To go further,
2/3 can be multipled by 5.
So 2 • 5 = 10
And 5 • 3 = 15
Therefore the new fraction is 10/15
When comparing to the 10/15, both of them are equivalent fractions.

Find the slope of the line that passes through the two points below. (3,4) and (3,-1)

tangare [24]

Answer:

Slope = (-5,0)

Step-by-step explanation:

When given two points and asked to find the slope, you can find the answer using slope formula which is:

slope = (y2 - y1) / (x2-x1)

You have been given the points (3,4) and (3,-1). You can select which ones to be x1 and y1 and which ones to be x2 and y2. It doesn't matter which, so let's just do (3,4) are x1 and y1 and (3,-1) are x2 and y2. Now we can plug it into the formula.

Slope = (-1 - 4) / (3-3)

= -5 / 0

= -5,0

So the answer is (-5,0).

4. A river tour boat is going down a stream to a park for lunch and then back up. It is a 60-mile round trip. On

DiKsa [7]

Answer:

The speed of the boat in still water is 10 miles / hour

Step-by-step explanation:

The trip there, and the trip back are the same -- 30 miles

Let the rate of the boat = x

Let the rate of the water = y

30 = 2*(x + y)

30 = 6*(x - y)

Divide the top equation by 2

Divide the bottom equation by 6

15 = x + y

5 = x - y Add the equations together.

20 = 2x Divide by 2

20/2 = x

x = 10
