Simplifying
3x + 8y + 13x = 0

Reorder the terms:
3x + 13x + 8y = 0

Combine like terms: 3x + 13x = 16x
16x + 8y = 0

Solving
16x + 8y = 0

Solving for variable 'x'.

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

Add '-8y' to each side of the equation.
16x + 8y + -8y = 0 + -8y

Combine like terms: 8y + -8y = 0
16x + 0 = 0 + -8y
16x = 0 + -8y
Remove the zero:
16x = -8y

Divide each side by '16'.
x = -0.5y

Simplifying
x = -0.5y

Identifying Parallel and Perpendicular Lines Which statement is true regarding the parallel and perpendicular lines in the diagr
Maslowich

Answer:

Option (3) and (4) are correct .

w║n and n⊥m and w║n so  w⊥m

Step-by-step explanation:

In the given figure, we have a set of lines which are parallel and perpendicular.

Parallel lines are lines in same plane which when extended do not meet and are always same distance apart from each other.

Perpendicular lines are two non-vertical lines in the same plane intersect at right angles.

From the figure given,

w║n and n⊥m as angle between a and n is right angle that is ∠mxn = 90° (given)

Since, w║n so  w⊥m also both w and n shows same property as both are parallel lines.

Thus, option (3) and (4) are correct .

Answer:

Step-by-step explanation:

Q. 17

Verticle angles are congruent

(6x+7) = (8x-17)

-6x from both sides

7 = 2x-17

add 17 to both sides

2x = 24

divide 24 by 2

x = 12

Q. 18

Linear pair = 180

(11x-15) + (5x-13) = 180

11x + 5x - 15 - 13 = 180

16x - 28 = 180

Add 28 to both sides

16x = 208

Divide 16

x = 13

Melody picks a number. She triples the number, squares the result, divides the square by 2, subtracts 30 from the quotient, and
Aleksandr-060686 [28]

The possible numbers that Melody could have picked are -4 and 4.

The operation that prevents us from knowing with 100% certainty the number Melody had picked is multiplication which is implied by the phrase "double the number".

Given, Let x be the number Melody had chosen.

Thus, tripling the number will give 3x, and

squaring this will result to (3x)² which is equals to 9x².

Dividing the square of the number by 2 and subtracting 30 from its quotient will give 42:

9x²/2 ₋ 30 = 42

9x²/2 = 42 ₊ 30

9x²/2 = 72

9x² = 72 × 2

9x² = 144

x² = 144/9

x² = 16

x = ±√16

x = ±4

x = ₊4 or x = 4

hence melody could have picked ₊4 or ₋4 numbers.
