Calculate the midpoint of the line segments joining the two points (-8, -7) and (4,9)

dmitriy555 [2]

Answer:

Step-by-step explanation:

To calculate the midpoint, you need to plug in the values of x and y into the midpoint formula.

M ( x1 + x2/2 , y1 + y2/2)

M [ -8 + 4/2 , -7 + 9/2]

M ( -2, 1)

If the first of three consecutive integers is subtracted from 138, the result is the sum of the second and third. What are the i

Murljashka [212]

Answer:

Step-by-step explanation:

n, n + 1, n + 2 - three consecutive integers

The equation:

138 - n = (n + 1) + (n + 2)

138 - n = n + 1 + n + 2 <em>combile like terms</em>

138 - n = 2n + 3 <em>subtract 138 from both sides</em>

-n = 2n - 135 <em>subtract 2n from both sides</em>

-3n = -135 <em>divide both sides by (-3)</em>

n = 45

n + 1 = 46

n + 2 = 47

A woman is standing at the edge of a slow-moving river which is one mile wide, and she wishes to return to her campground on the

vesna_86 [32]

Answer:

the best option would be to swim

Step-by-step explanation:

Hello! To solve this problem we must follow the following steps.

1. remember the concept of uniform motion with constant speed, which establishes the following equation

$t=\frac{X}{V}$

where

t=time

x=distance

V=speed

2. Calculate the time it takes to swim and calculate the time it takes to walk

walking:

x=10mile

v=5milles/h

$t=\frac{10}{5} =2h$

swimming

x=1mile

v=3milles/h

$t=\frac{1}{3} =0.3h$

3. Compare both results and choose the one with the least time.

as you can see it takes less time swimming, so this would be the best way
