Step-by-step explanation:

The formula for calculating the midpoint of two coordinates is expressed as shown;

M(X, Y) = [(x1+x2)/2, (y1+y2)/2]

Given the midpoint of ST to be ((6, -2) and one endpoint T is (0,2), according to expression above;

X = (x1+x2)/2

Y = (y1+y2)/2

From the coordinates, X = 6, Y = -2, x1 = 0 and y1 = 2, to get x2 and y2;

X = (x1+x2)/2

6 = (0+x2)/2

cross multiply

12 = 0+x2

x2 = 12-0

x2 = 12

For 2;

Y = (y1+y2)/2

-2 = (2+y2)/2

cross multiply

-4 = 2+y2

y2 = -4-2

y2 = -6

Hence the other endpoint S(x2, y2) is (12, -6)

Someone solve this please like NOW 4(5x-7)+12=16x+24

Bingel [31]

20x-28+12=16x+24 (i distributed the 4 to get this)

20x-16=16x+24 (added -28 & 12)

4x=40 (Subtracted 16x from both sides and added 16 to both sides)

(divide by 4 on both sides)

x=10

7 (5х + 2) = 3х + 14 Need help solving

FinnZ [79.3K]

Answer: 0

35X +14=3X +14
35X = 3X
35X-3X=0
32X = 0 divide both sides by 32
x=0

2 taps A and B can fill a swimming pool in 3 hours. If turned on alone, it takes tap A 5 hours less than tap B to fill the same

vazorg [7]

Answer:

Tap A will take 2 hours and tap B will take 6 hours to fill the tank when turned on alone.

Step-by-step explanation:

Let tap B fills the pool alone in the time = x hours

So in one hour part of pool will be filled = $\frac{1}{x}$

Another tap A when turned on, it takes time to fill the pool = x-5 hours

So in one hour part of the same pool filled = $\frac{1}{x-5}$

Now both the taps A and B are turned on then time taken to fill the pool = 3 hours.

Part of the pool filled in one hour by both the taps = $\frac{1}{3}$

Now we form an equation

Part of pool filled in one hour by tap A + Part of pool filled in one hour by tap B = Part of pool filled in one hour by both the taps when turned on

$\frac{1}{(x-5)}+\frac{1}{x}=\frac{1}{3}$

$\frac{x-5+1}{x(x-5)}=\frac{1}{3}$

$\frac{x-4}{x(x-5)}=\frac{1}{3}$

3(x - 4) = x(x - 5)

x² -5x = 3x - 12

x² - 8x + 12 = 0

x² - 6x - 2x + 12 = 0

x(x - 6) - 2(x - 6) = 0

(x -2)(x - 6) = 0

x = 2, 6 hours

We will take higher value of x as x = 6 hours for tap B.

Time taken by tap A = 6 - 4 = 2 hours.

Therefore, Tap A will take 2 hours and tap B will take 6 hours to fill the tank when turned on alone.

4) Durante un día de enero la temperatura bajó de 5º a -5º. ¿Cuál fue el cambio en temperatura?

mezya [45]

Temperature goes down up to 10° Celsius during the night.

Given that;

Temperature drop from 5º Celsius to -5º Celsius

Find:

Change in temperature in Celsius

Computation:

Change in temperature = Initial temperature in Celsius + Final temperature in Celsius

Change in temperature = 5 - (-5)

Change in temperature = 5 + 5

Change in temperature = 10° Celsius
