Answer:

x= 6/1=0.167

Step-by-step explanation:

Simplify:1/x

(x/x+2)- 1/x) +3 =0

Simplify:x/x

(1+2)-1/x)+3=0

Subtracting a fraction from a whole

Rewrite the whole as a fraction using  x  as the denominator :

 3 =  3/1  = 3*x/x

     

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

3 • x - (1)/x = 3x - 1/x

(3x - 1) /x+  3  = 0

Adding a whole to a fraction

Rewrite the whole as a fraction using  x  as the denominator :

3= 3/1 =3 • x

Adding up the two equivalent fractions

(3x-1) + 3 • x/x = 6x - 1/x

 

6x - 1/x = 0

   

When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

6x-1/x• x = 0 • x

Now, on the left hand side, the  x  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  6x-1  = 0

Solve  :    6x-1 = 0

Add  1  to both sides of the equation :

                     6x = 1

Divide both sides of the equation by 6:

                    x = 1/6 = 0.167

A walkway surrounds a rectangular garden. The width of the garden is 3 meters, and the length
rusak2 [61]

Answer:

You are given the width of the garden which is w= 8 feet

length of the garden which l= 6 feet

the width of the walkway is x

so for every side of the garden there is an x

so length overall would be 8+2x (length of garden + x one side + x other side)

and width overall would be 6 + 2x (width of garden + x of one side + x of other side)

area of rectangle is length*width

so the expression would be (8+2x)*(6+2x)

:))) smile....

I hope it is correct.

eimsori [14]

Answer: The rate = 8.5 ft/h

Step-by-step explanation:

Since we are going to need to differentiate to find the rate of change of θ we need to express it in radians rather than degrees.

Therefore, 15 degree per hour will be expressed as

15° × π/180 = 0.2618rad/hour

Using trigonometry function to find Ø

Tan Ø = 40/30 = 1.333

Ø = 53 degree

Convert it to radian

Ø = 0.93 rad

The changing at a rate of 15o per hour will be

Rate = radian/ time

0.2618 = (0.93 -0)/t

t = 0.93/0.2618

t = 3.5 hours

The rate of change in the length of the shadow at that same time will be:

Rate = 30/3.5 = 8.5 ft/ hour
