What is the midpoint of a segment whose endpoints are (3,-1) and (-5,-3)
garik1379 [7]
To find the midpoint, you're trying to bisect the line (cut it in half). The equation you'll need for this is (x1 + x2 / 2, y1 +y2 / 2). You're using the starting point of the line and the ending point of the line, and dividing it by two to get to the middle.

(3+-5/2 , -1 + -3/2)
(-2/2 , -4/2)
(-1,-2) is your midpoint

Brenda and Hazel decide to throw a surprise party for their friend, Aerica. Brenda and Hazel each go to the store with the same
Oliga [24]

Answer:

  $130

Step-by-step explanation:

You want to know Brenda and Hazel's combined money when the ratio of their remaining balances is 1 : 4 after Brenda spent $58 and Hazel spent $37. They had the same amount to start with.

<h3>Setup</h3>

Let x represent the total amount the two women started with. Then x/2 is the amount each began with, and their fnal balance ratio is ...

  (x/2 -58) : (x/2 -37) = 1 : 4

<h3>Solution</h3>

Cross-multiplying gives ...

  4(x/2 -58) = (x/2 -37)

  2x -232 = x/2 -37 . . . . . . eliminate parentheses

  3/2x = 195 . . . . . . . . . . . . add 232-x/2

  x = (2/3)(195) = 130 . . . . . multiply by 2/3

Brenda and Hazel had $130 altogether before their purchases.

__

<em>Alternate solution</em>

The difference in their spending is $58 -37 = $21. This is the same as the difference in their final balances. That difference is 4-1 = 3 "ratio units", so each of those ratio units is $21/3 = $7. Their ending total is 1+4 = 5 ratio units, or $35. The total they started with is $58 +37 +35 = $130.

Suppose two trains leave a certain​ station, at the same​ time, traveling in opposite directions. one train travels 1010 mph fas
Rom4ik [11]

In the question, it is given that

Suppose two trains leave a certain​ station, at the same​ time, traveling in opposite directions. one train travels 10 mph faster than the other. in 2.5hours, the trains are 255 miles apart.

Let the speed of the slower train be x m/h and faster train be (x+10) m /h.

Distances travelled by them are

d_{slower} = 2.5 x \ miles, d_{faster} = 2.5(x+10) miles

And total distance is 255 miles, that is

2.5x +2.5(x+10) = 255&#10;\\&#10;x+x+10=102&#10;\\&#10;2x = 92&#10;\\&#10;x = 46 MPH

So the speed of slower train is 46 MPH and of faster train is 56MPH.
