-2(x - 2) - 4x = 3(x + 1) - 9x

Mathematics

4 0

\huge\boxed{\text{no solution}}

Distribute the -2 and the 3. -2x-2(-2)-4x=3x+3(1)-9x

Multiply. -2x+4-4x=3x+3-9x

Combine the like terms. -6x+4=-6x+3

Add 6x on both sides of the equation. 4=3

This statement is false, so this equation has \boxed{\text{no solution}}.

CAN SOMEONE HELP. i will give 150 points if some one can explain and solve you have to find the missing angle measures.
Tems11 [23]

Answer:

\angle ACB=40^{\circ}, \angle ABC=63^{\circ}

Step-by-step explanation:

Finding x:

We know that \angle DAB=180^{\circ}, because it's a straight line. So, \angle CAB=180^{\circ}-103^{\circ}=77^{\circ}.

We know that the sum of the angles of any triangle will be 180^{\circ}.

So, we have that (3x-14)+(3x+9)+77=180.

Combining like terms on the left gives 6x+72=180.

Subtracting 72 from both sides gives 6x=108.

Dividing both sides by 6 gives x=18.

Finding missing angle measures:

\angle ACB=3x-14=3(18)-14=54-14=40.

\angle ABC=3x+9=3(18)+9=54+9=63.

So, \angle ACB=40^{\circ} and \angle ABC=63^{\circ} and we're done!

Note: \angle ACB+\angle ABC=\angle CAD. Coincidence? If not, try and prove it!

Solve and show your work.<br><br> 12-[2 + 6 ÷ (10 - 2³)]
Svet_ta [14]

Answer:

7

Step-by-step explanation:

  1. 2^{3} = 8  
  2. Plug 8 in: 12 - [2 + 6 ÷ (10 - 8)]
  3. 10 - 8 = 2
  4. Plug 2 in: 12 - [2 + 6 ÷ (2)]
  5. 6 ÷ 2 = 3
  6. Plug 3 in: 12 - [2 + 3]
  7. 2 + 3 = 5
  8. Plug 5 in: 12 - 5
  9. 12 - 5 = 7

I hope this helps!
