Add .25x to both sides to balance it out then divide by .4 the other side should be in fractio

0.5 = 0.4y - 0.25x

Since we're solving for (y), we have to get that variable alone

0.5 = 0.4y - 0.25x

+ 0.25x + 0.25x

So add the 0.25x on both sides

0.25x + 0.5 = 0.4y

----------------- -------

0.4 0.4

Then divide everything by 0.4

0.625x + 1.25 = y

That's your answer (this is slope-intercept form, y = mx + b)

Please answer fast need it now like now now!!!!! 10+x<5

katrin [286]

Subtract 10 from both sides
10 + x < 5
10 - 10 + x < 5 - 10
x < -5
So the answer is x < -5, or x is less than -5. Any number less than -5 would be the solution. Hope this helps!

35 POINTS!!! The measures of the angles in a quadrilateral are represented by x, 2x, 3x, and 3x. Write an equation that would al

Marina86 [1]

Answer:

The value of x is 40.

Step-by-step explanation:

The measures of the angles in a quadrilateral are represented by x, 2x, 3x, and 3x.

According to the angle sum property of quadrilateral, the sum of interior angles of a quadrilateral is always 360 degree.

Since the measures of the angles in a quadrilateral are represented by x, 2x, 3x, and 3x, therefore

$x+2x+3x+3x=360$

This is the equation which is used to solve for the value of x.

$9x=360$

$x=\frac{360}{9}$

$x=40$

Therefore the value of x is 40.
