<em><u>Answer:</u></em>

x = 8

<em><u>Step-by-step explanation:</u></em>

Okay, so with the info here, we know that angle RXS is 4x + 1, angle SXT is x + 9, and angle RXT is 50.

Angle RXT is angle RXS + angle SXT because it's on the diagram. So from

RXT = RXS + SXT, we can creat the equation:

50 = (4x + 1) + (x + 9) [Because we plug in the values]

So from here, we have to solve the equation:

50 = (4x + 1) + (x + 9)

First, we want to simplify everything so:

50 = 5x + 10

Then we want to isolate the variable so:

50 - 10 = 5x + 10 - 10

40 = 5x

40/5 = 5x/5

8 = x

<u>x = 8</u>

Determine whether quantities vary directly or inversely and find the constant of variation. If 5 bushels of wheat weigh 136 kg,
pentagon [3]

Let the bushels of wheat is b and weight of the wheat is w.

We can say that more the bushels of wheat more will be the weight of the wheat.

Hence, the quantities  vary directly.

Therefore, we have

b=kw,  where k is the constant of variation.

Now, we have been given that 5 bushels of wheat weigh 136 kg. Thus, we have

5=136k\\&#10;\\&#10;k=\frac{5}{136}

Thus, the constant of variation is  \frac{5}{136}

Now, we have been given 3.5 bushels of wheat. Hence, we have

3.5=\frac{5}{136} w\\&#10;\\&#10;w=\frac{136\times 3.5}{5} \\&#10;\\&#10;w=95.2

Therefore, 3.5 bushels of wheat weigh 95.2 kg

Triangle K L J is cut by line segment N O. Line segment N O goes from side L K to side L J. The length of L N is (x minus 3) inc
kozerog [31]

Answer: x= 8

Step-by-step explanation:

According to the converse of basic proportionality theorem,

If in ΔABC , DE is a line drawn from AB to AC such that \dfrac{AD}{DB}=\dfrac{AE}{EB}

then, DE is parallel to the third side BC.

Applying converse of basic proportionality theorem, to get NO parallel to KJ, we must have

\dfrac{LO}{OJ}=\dfrac{LN}{NK}\\\\\Rightarrow \dfrac{x-4}{x}=\dfrac{x-3}{x+2}\\\\\Rightarrow\ (x-4)(x+2)=x(x-3)\\\\\Rightarrow\ x^2-2x-8=x^2-3x\\\\\Rightarrow\ -2x+3x=8\\\\\Rightarrow\ x=8

Hence, the value of x should be 8, so that Line segment N O is parallel to line segment K J.

Step-by-step explanation:

Use the rhombus properties:

diagonals are perpendicular and divide in half.

In order for the rhombus not to be a square, the diagonals must be of different lengths.
