Answer: D) 18

Step-by-step explanation:

6 - x = -12

Subtract 6 from both sides.

-x = -18

Divide by -1 on both sides so as to isolate x.

x = 18

Answer:

D. 18

Step-by-step explanation:

The first thing you need to do is subtract 6 from both sides. This makes it cancel out on the left, since 6 - 6 = 0, and subtract 6 from -12:

6 − x = −12

-6        - 6

________

-x = -18

Then divide both sides by -1, because there's a negative sign (-) in front of the x, meaning there's like an invisible 1 there:

-1x = -18

x = 18

What is the first step in constructing an inscribed circle inside triangle XYZ?
Tasya [4]

Answer:

Construct the angle bisector of angle Y

Step-by-step explanation:

-An inscribed circle is defined as the largest circle that can be drawn within the boundaries of a plane figure.

-The first step in constructing an inscribed circle is to bisect any two angles of the plane figure, triangle in this case, as there intersection point will form the circle's center.

=>Hence, the first step is Construct the angle bisector of angle Y or Z or X( whichever you decide on).

A sixth number will be added to the list. What must it be in order for the mean to be 12?
Vlad1618 [11]

Answer:

16

Step-by-step explanation:

7+16+11+12+10= 56

In order to find the 6th number, you must multiply 12 and 6.

12*6= 72

72-56= 16

Double check your work:

7+16+11+12+10+16= 72

72/6= 12

Please help quick Solve for x.​
Kamila [148]

Answer:

x = 3.75

Step-by-step explanation:

So, lets start with what we know.

Line = 180 degrees

Triangle = 180 degrees, a + b + c = 180

So, we can form the equations,

17x - 1 + <CDB = 180

-17x + 1                -17x + 1

             <CDB = 181 - 17x

and

84 +7x + 5 + <CDB = 180

89 + 7x      + <CDB = 180

-89                              -89 + 7x

                     <CDB = 91 + 7x

Here, we are given 2 values of <CDB, but they must be the same, so let's substitute them into each other

181 - 17x = 91 + 7x

-91 +17x   -91  +17x

90         =        24x

90 / 24  =        24x / 24

3.75       =           x

x            =           3.75

There, you have it, x is 3.75

Solve the formula for the specified variable. V=XLJ for X
jeka57 [31]
Given the equation, V = XLJ:

In order to solve for X, divide both sides of the equation by LJ:

V / (LJ) = (XLJ) / LJ

Doing so gives you the final answer:

V / LJ = X
