3(x - 4) + 5 = 2x - 2(3 - x) \\ 3x - 12 + 5 = 2x - 6 + 2x \\ 3x - 7 = 4x - 6 \\ 3x - 4x - 7 + 6 = 0 \\  - x - 1 = 0 \\ x =  - 1

Answer:

-1

Step-by-step explanation:

Solve

3x - 7 = 4x - 6

3x - 7 + 7 = 4x - 6 + 7

3x = 4x + 1

3x - 4x = 4x + 1 - 4x

-x • 1

-1

Ben drinks water everyday. He drinks 3 1/2 liters of water every 1/4 of an hour. Ben drinks water at a constant rate. How many l
Setler79 [48]

Ben drinks 3 1/2 liters of tea every 40 minutes.

This means that he would drink 1 3/4 of tea every 20 minutes (divide both sides by 2).

Now, let's multiply each side by 3.  

1.75 * 3 = 5.25 (aka 5 1/4)

20 * 3 = 60 minutes (an hour)

He drinks 5 1/4 liters of tea in one hour.

Does anyone know how to do this (#2) PLZZZZ HELPPPPPPPP
timurjin [86]

Answer:

a.- slope= 36

Interpretation : The cable car travels 36 meter per minute

b.- y = 36x + 100

c.- 640 meters

Step-by-step explanation:

a.-

Find slope using the slope formula : \frac{y2-y1}{x2-x1}

Plug in the two given points: \frac{1000-100}{25-0}

Subtract the numbers : \frac{900}{25}

Reduce the fraction : 36

b.-

Using the given y-interspet (100) and the slope create an equation: y = 36x + 100

c.-

Using the equation you created plug in 15 for x to find the

distance: y = 36 (15) + 100

Multiply the numbers : y = 540 + 100

Add the numbers : y = 640

WRITE AN COMPOUND INEQUALITY FOR THIS SENTENCE
Mila [183]
Hello there!

Write a compound inequality for this sentence: 'w' is less than 4 and greater than or equal to -8
Only use 'w' once.


W is less than four ~ 4 \ \textgreater \ w

W is greater than or equal to -8 ~ w \geq -8

If we were to put this together, it would look like:

4 \ \textgreater \  w  \geq  -8


I hope I helped!

Let me know if you need anything else!

a triangle has a perimeter of 10x+2 . two sides have lengths of 5x and 2x+9 what is the length of the 3rd side
stiks02 [169]
Since all the sides add up to 10x+2, that means that 10x-2-<side1>-<side2>=<side3>. Plugging it in, we have 10x-2-5x-(2x+9)=side3, and 5x-2-(2x+9)=side3, then expanding it to 5x-2-2x-9=3x-11=side3
