Answer:

3x - 9

Step-by-step explanation:

in expressions, we don't get the value of the unknown so, we just workout  by putting the like terms together.

(4x + 2x - 3x) - 9 = 3x -9.

Pls help its my last question?!?!
OlgaM077 [116]

Answer:

x = -11

m<B = -43

m<C = -22

Step-by-step explanation:

To solve for <em>x</em>, solve (3x-10) + (2x) + 65 to get 5x+55. Simplify to 5x = -55. This can simplify further to x = -11. Insert -11 as x into the angles.

I hope this is correct and helps!

Perpendicular lines and slopes:

If two lines are perpendicular, the multiplication of their slopes is -1.

What is the slope of the dashed line

Solve for x if AB = 5x and BC = 3x + 24.
NikAS [45]

The value of x according to the given task is; 12.

<h3>What is the value of x?</h3>

It follows from the task content that the value of x is to be determined.

Since, lines AB and BC are both tangent to the circle and they both share a point of intersection; it follows that;

5x = 3x +24

  • collect like terms

2x = 24

  • divide both sides by 2

x = 24/2

x = 12.
