Answer:The result can be shown in multiple forms.

Exact Form:

x = 1/ 5

Decimal Form:

x = 0.2

Step-by-step explanation:

6 x − 1 + 7 x = 2 x + 2 − 4 x

Add  6 x  and  7 x .

13 x − 1 = 2x + 2 − 4 x

Subtract  4 x  from  2 x .

13 x − 1 = − 2 x + 2

Move all terms containing  x  to the left side of the equation.

15 x − 1 = 2

Move all terms not containing  x  to the right side of the equation.

15 x = 3

Divide each term by  15  and simplify.

x = 1 /5

Answer:

<h2>140°</h2>

solution,

Let <DEF= x°

<CDE= 2x°

<BAF= 90°

The sum of interior angle of hexagon= 720°

<A + <B + <C + <D + <E +<F = 720°

90 + 145 + 115 + 2x + x + 160 = 720 \\ 510 + 3x = 720 \\3x + 510 = 720 \\ 3x + 510 - 510 = 720 - 510 \\ 3x = 210 \\  \frac{3x}{x}  =  \frac{210}{3}  \\ x = 70 \: degree

Again,

< \: cde = 2x \\  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  = 2 \times 70 \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  = 140 \: degree

Hope this helps...

Good luck on your assignment..

Valentin [98]
If a cup is a regular sized cup that is 2 deciliters, and 1 liter equals 10 deciliters, that means that 1 liter = 5 cups, which means that 3 liters = 15 cups. If it is a cup that has 0.33 dl, then the correct number would be 9 cups.
