Answer:

$\frac{-3x}{14}$

Step-by-step explanation:

$x+\frac{1}{2}x+7y = 0\\$

$1.5x + 7y = 0$

$7y = -1.5x$

$y = \frac{-1.5x}{7}$

$= \frac{-3x}{14}$

Hope this helps :)

Answer:

y = -3/2x

Step-by-step explanation:

x+1/2x+7y=0

Move expression to the right-hand side and change its sign

7y= -x -1/2x

Calculate the difference

7y = -3/2x

Then divide both sides by 7

7y/7 = -3/2x ÷ 7

Solution

y = -3/14x

Hope this helps

The overall ratio is:

24/2 = 12

12 x 4 = 48

There would be 48 apple trees.

Answer:

x=70, y=55

Step-by-step explanation:

Since the angle "y" and 2x-15 form a straight line, that means the sum of the angles, must be 180 degrees.

So using this we can derive the equation: $y+2x-15=180$

The next thing you need to know is that the sum of interior angles of a triangle is 180 degrees, so if we add all the angles, we should get 180.

So using these we can derive the equation: $x+2y=180$

So, in this case we simply have a systems of equations. We can solve this by solving for x in the second equation (sum of interior angles), and plug that into the first equation.

Original Equation:

$x+2y = 180$
