X = -12

-6x = 72
Divide by -6 on both sides
-6x/-6 = x
72/-6 = -12
x = -12

Solving the given equation, the value of v that makes the statement true is:

A. v = 8.

<h3>What is the given equation?</h3>

The equation is:

$12 = 12 + \frac{v - 8}{2}$

Hence:

$\frac{v - 8}{2} = 0$

Applying cross multiplication:

v - 8 = 0

v = 8.

Hence option A is correct.

Find the Area of the figure below, composed of a parallelogram and two semicircles. Round to the nearest tenths place.

Mila [183]

Step-by-step explanation:

the total area = the area of full circle + the area of parallelogram = (π ×(8/2)²) + (28×7)

= (3,14 ×16)+(196)

= 50,24 +196

= 246,24

= 246,2

Whats 4(d+2)-2d=3(2+d)

Dmitry [639]

Simplify:

$4(d + 2) - 2d = 3(2 + d)\\4d + 8 - 2d = 6 + 3d\\d + 8 - 2d = 6\\-d + 8 = 6\\-d = -2\\d = 2$

d is equal to 2.

When testing for current in a cable with eleven color-coded wires, the author used a meter to test four wires at a time. How ma

Sav [38]

Answer:

The number of tests required is 330.

Step-by-step explanation:

We have to find the total number of combinations of four wires.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

Four wires from a set of 11.

$C_{11,4} = \frac{11!}{4!(11-4)!} = 330$

The number of tests required is 330.
