Your answer is x=-14.
To solve for X, first you want to write out your equation. Next, you want to multiple both sides by two so you can get rid of them fraction. Doing this will cancel out your fraction, and you get: -x -6=8. Next you want to move the constant to the right, by adding 6. Then you get -x=14. X can’t be a negative, so divide -1 by moving the negative sign to the other side. Thus, you get x=-14

Hope this helps :)

Answer:

x=-3.5

reason:

first, add 3 to both sides
this makes the equation -1/2x=7
then, divide both sides by -1/2
this will give you x=-3.5

Step-by-step explanation:

9x-3=60°{each angle of equilateral triangle is 60°}
9x=60+3
x=63/9
x=7

so,

9x-3
9×7-3
63-3
60°

hope it helps.

Guys, Can you please help me with these questions

MakcuM [25]

Answer:

a) $w^{13} x^{5} y^{6}$

b) $\frac{x}{3y^{6} }$

Step-by-step explanation:

a) $(w^{2} xy^{3} )^{2}(w^{3}x )^{3}$

1. Distribute the second power (2) outside the first pair of parenthesis:

$(w^{2(2)} x^{2} y^{3(2)} )$

= $w^{4} x^{2} y^{6} (w^{3}x )^{3}$

2. Distribute the third power (3) outside the second pair of parenthesis:

$(w^{3(3)} x^{3} )$

= $w^{4} x^{2} y^{6} w^{9} x^{3}$

3. Combine like terms:

$w^{13} x^{5} y^{6}$

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

b) $\frac{2x^{2} y^{5} }{6xy^{11} }$

1. Factor the number 6 (= 2 · 3):

$\frac{2x^{2} y^{5} }{2(3)xy^{11} }$

2. Cancel the common factor (2):

$\frac{x^{2} y^{5} }{3xy^{11} }$

3. Cancel out $xy^{5}$ in the numerator an denominator:

$\frac{x}{3y^{6} }$

hope this helps!

Which is greater 7/8 or 5/10

Sloan [31]

Find a common denominator 7/8 = 35/40 and 5/10 = 20/40. Also 7/8 is almost a whole and 5/10 is half. 7/8 is greater.

Can someone help me find this

PSYCHO15rus [73]

Step-by-step explanation:

In triangle,

<u> XYZ</u> <u>PYZ</u>

XZ = PZ = 12cm

XY = PY = 5cm

YZ = YZ (Common side)

<em><u>Hence</u></em><em><u>,</u></em>

As three sides of the two triangles are equal so,

<em><u>Triangle XYZ is congruent to Triangle PYZ by SAS congruence condition </u></em>
