Please help me in this question 3(x-2)=2x+10

Lelu [443]

Answer:

$3(x-2)=2x+10\\3x-6=2x+10 | +6\\3x=2x+16 | -2x\\x = 16$

30.

a) $180^{0} - 134^0-22^0=24^0$

$r=24^0$

$90^0=2x^0+3x^0\\90^0=5x^0 |:5\\x^0=18^0$

$2x^0= 2* 18^0=36^0$

$3x^0=3*18^0=54^0$

Take care!

Which value of x would make TV || OS? 3 8 10 11

garik1379 [7]

Answer:

For x = 10, the lines will be parallel

Step-by-step explanation:

For parallel lines in a triangle, their sides must be proportional

And,

$\frac{x+4}{x-3} = \frac{x+10}{x}$

Cross Multiplying

=> x(x+4) = (x-3)(x+10)

=> $x^2+4x = x^2+7x-30$

=> $x^2-x^2+7x-4x = 30\\$

=> 3x = 30

Dividing both sides by 3

=> x = 10

What is the slope between the points (2, 3) and (-1, 12)

Scrat [10]

Answer:

$\huge \boxed {slope = - 3}$

Step-by-step explanation:

$m = \frac{rise}{run}$

The slope is the change of y over the change of x.

$m = \frac{12 - 3}{ - 1 - 2} \\ m = \frac{9}{ - 3} \\ m = - \frac{9}{3} \\ m = - 3$

Therefore, the slope is -3.
