6x-2(-3x-5)=154 What the answer

Mathematics
1 answer:
Fofino [41]3 years ago
7 0

Answer:

x = 12

Step-by-step explanation:

Simplifying

6x + -2(-3x + -5) = 154

Reorder the terms:

6x + -2(-5 + -3x) = 154

6x + (-5 * -2 + -3x * -2) = 154

6x + (10 + 6x) = 154

Reorder the terms:

10 + 6x + 6x = 154

Combine like terms: 6x + 6x = 12x

10 + 12x = 154

Solving

10 + 12x = 154

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-10' to each side of the equation.

10 + -10 + 12x = 154 + -10

Combine like terms: 10 + -10 = 0

0 + 12x = 154 + -10

12x = 154 + -10

Combine like terms: 154 + -10 = 144

12x = 144

Divide each side by '12'.

x = 12

Simplifying

x = 12

Papessa [141]
  • Midpoint Formula: (\frac{x_2+x_1}{2} ,\frac{y_2+y_1}{2} )

Plug the coordinates into the midpoint formula and solve as such:

(\frac{2+8}{2} ,\frac{-5+3}{2} )\\\\(\frac{10}{2} ,\frac{-2}{2} )\\\\(5,-1)

<u>Your midpoint is (5,-1).</u>

What is the answer to this question
Ratling [72]
Hello!

As you cans see, the angle is a right angle, which measures 90°. One of the angles measure 35°

90 - 35 = 55

That means 5x = 55°

Divide both sides by 5

\frac{5x}{5} =  \frac{55}{5}

\framebox{x = 11 \°}
