2(n+5)=-2 I need the steps

Mathematics
1 answer:
Eva8 [605]3 years ago
6 0

Answer:

n = -6

Step-by-step explanation:

2 ( n + 5 ) = -2

First, solve the brackets.

2n + 10 = -2

Now take 10 to the right side.

2n + 10 -10 = -2 - 10

2n = -12

Then divide both sides by 2.

\frac{2n}{2} =\frac{-12}{2}

And now you'll the value of n.

n = ( -6 )

Solve for A<br> 3(4A + 4) = 3A + 8A + 1 + 8
kvasek [131]

Answer:

a=−3

Step-by-step explanation:

Let's solve your equation step-by-step.

3(4a+4)=3a+8a+1+8

Step 1: Simplify both sides of the equation.

3(4a+4)=3a+8a+1+8

(3)(4a)+(3)(4)=3a+8a+1+8(Distribute)

12a+12=3a+8a+1+8

12a+12=(3a+8a)+(1+8)(Combine Like Terms)

12a+12=11a+9

12a+12=11a+9

Step 2: Subtract 11a from both sides.

12a+12−11a=11a+9−11a

a+12=9

Step 3: Subtract 12 from both sides.

a+12−12=9−12

a=−3

Answer:

a=−3

The force F of gravity on a rocket varies directly with its mass m and inversely with the square of its distance d from Earth. W
xz_007 [3.2K]

Model for the Combined variation  is  F = \frac{km}{d^{2} }

Equation to find the mass of the rocket in terms of F and d is :

m=\frac{F d^{2} }{k}

<h3>What is Force ?</h3>

A force is the quantity that change the motion of the object. Force is that influence which can cause any object having some mass, to change it's position or to accelerate from it's original position.

Force (F) and mass (m) of any object are  directly proportional to each other. More the mass of the object , more the force will require to accelerate it.

Mathematically, we can write the equation of force as :

F = m . a

where , m = mass of the object

             a = constant value

In the statement given,

As, force of gravity varies directly with its mass

Therefore, F= k m , where k is a constant

Also force is inversely varies with square of distance d

Thus, F = k / d²

Combining both equations :

F = \frac{km}{d^{2} }  

and the equation of mass in terms of F and d can be written as :

m=\frac{F d^{2} }{k}

A line includes the points (8,5) and (9, – 5). What is its equation in point-slope form?
zmey [24]

Answer:

Step-by-step explanation:

slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

         =\frac{-5-5}{9-8}\\\\=\frac{-10}{1}\\\\=-10\\

Point-slope form:

y - y1 = m(x - x1)

y - 5 = -10(x - 8)
