Solve 3(2x - 8) = 12​

Mathematics
1 answer:
spayn [35]3 years ago
5 0

Answer:

x=6

Step-by-step explanation:

Simplifying

3(2x + -8) = 12

Reorder the terms:

3(-8 + 2x) = 12

(-8 * 3 + 2x * 3) = 12

(-24 + 6x) = 12

Solving

-24 + 6x = 12

Solving for variable 'x'.

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

Add '24' to each side of the equation.

-24 + 24 + 6x = 12 + 24

Combine like terms: -24 + 24 = 0

0 + 6x = 12 + 24

6x = 12 + 24

Combine like terms: 12 + 24 = 36

6x = 36

Divide each side by '6'.

x = 6

Simplifying

x = 6

Determine which of the lines, if any, are parallel or perpendicular. Explain.
hodyreva [135]
Answer:
line a and b are parallel
line c is not perpendicular because it is not 3

step-by-step explanation:
if the slope is the same it is parallel
if the slope is the complete opposite it is perpendicular
lines a and b are parallel with a slope of -1/3
(0, 5) (3, 4)
m = 4 - 5 / 3 - 0
m = -1 / 3
m = -1/3
(-1, 1) (2, 0)
m = 0 - 1 / 2 + 1
m = -1 / 3
m = -1/3
line c is perpendicular to lines a and b the slope is
(0, 0) (2, 5)
m = 5 - 0 / 2 - 0
m = 5/2
