-2(x-4)=-16 SOLVE FOR X!!

Mathematics
1 answer:
Andrej [43]3 years ago

Answer:

x = 12

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

-2(x - 4) = -16

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute -2:                    -2x + 8 = -16
  2. Isolate <em>x</em> term:                  -2x = -24
  3. Isolate <em>x</em>:                           x = 12

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute:                    -2(12 - 4) = -16
  2. Subtract:                       -2(8) = -16
  3. Multiply:                        -16 = -16

Here we see that -16 does indeed equal -16.

∴ x = 12 is a solution of the equation.

<span>96 degrees Looking at the diagram, you have a regular pentagon on top and a regular hexagon on the bottom. Towards the right of those figures, a side is extended to create an irregularly shaped quadrilateral. And you want to fine the value of the congruent angle to the furthermost interior angle. So let's start. Each interior angle of the pentagon has a value of 108. The supplementary angle will be 180 - 108 = 72. So one of the interior angles of the quadrilateral will be 72. From the hexagon, each interior angle is 120 degrees. So the supplementary angle will be 180-120 = 60 degrees. That's another interior angle of the quadrilateral. The 3rd interior angle of the quadrilateral will be 360-108-120 = 132 degrees. So we now have 3 of the interior angles which are 72, 60, and 132. Since all the interior angles will add up to 360, the 4th angle will be 360 - 72 - 60 - 132 = 96 degrees. And since x is the opposite (or congruent) angle to this 4th interior angle, it too has the value of 96 degrees.</span>

Arisa [49]

Answer:

Step-by-step explanation:

Suppose the dimensions of the playground are x and y.

The total amount of the fence used is given and it is 780 ft. In terms of x and y this would be 3x+2y=780 (we add 3x because we want it to be cut in the middle). Therefore,  y= 780/2-3/2x. Now, the total area (A )to be fenced is

A=x*y= x*(390-3/2x)=-3/2 x^2+390x

Calculating the derivative of A and setting it equals to 0 to find the maximum

A'= -3x+390=0

This yields x=130.

Therefore y=780/2-3/2*130=195

Thus, the maximum area is 130*195=25,350ft^2

Answer:

En física, una fuerza es cualquier interacción que, sin oposición, cambiará el movimiento de un objeto. Una fuerza puede hacer que un objeto con masa cambie su velocidad (lo que incluye comenzar a moverse desde un estado de reposo), es decir, acelerar. ... Una fuerza tiene magnitud y dirección, lo que la convierte en una cantidad vectorial.
