Answer:

20

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

               1/10*x+5-(-3*x-13+4*x)=0  

Step by step solution :

Step  1  :

            1

Simplify   ——

           10

Equation at the end of step  1  :

    1                

 ((—— • x) +  5) -  (x - 13)  = 0  

   10                

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  10  as the denominator :

        5     5 • 10

   5 =  —  =  ——————

        1       10  

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 fractions that have a common denominator :

2.2       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:

x + 5 • 10     x + 50

——————————  =  ——————

    10           10  

Equation at the end of step  2  :

 (x + 50)    

 ———————— -  (x - 13)  = 0  

    10        

Step  3  :

Rewriting the whole as an Equivalent Fraction :

3.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  10  as the denominator :

             x - 13     (x - 13) • 10

   x - 13 =  ——————  =  —————————————

               1             10      

Adding fractions that have a common denominator :

3.2       Adding up the two equivalent fractions

(x+50) - ((x-13) • 10)     180 - 9x

——————————————————————  =  ————————

          10                  10    

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  180 - 9x  =   -9 • (x - 20)  

Equation at the end of step  4  :

 -9 • (x - 20)

 —————————————  = 0  

      10      

Step  5  :

When a fraction equals zero :

5.1    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:

 -9•(x-20)

 ————————— • 10 = 0 • 10

    10    

Now, on the left hand side, the  10  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  -9  •  (x-20)  = 0

Equations which are never true :

5.2      Solve :    -9   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

5.3      Solve  :    x-20 = 0  

Add  20  to both sides of the equation :  

                     x = 20

One solution was found :

                  x = 20Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

               1/10*x+5-(-3*x-13+4*x)=0  

Step by step solution :

Step  1  :

            1

Simplify   ——

           10

Equation at the end of step  1  :

    1                

 ((—— • x) +  5) -  (x - 13)  = 0  

   10                

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  10  as the denominator :

        5     5 • 10

   5 =  —  =  ——————

        1       10  

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 fractions that have a common denominator :

2.2       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:

x + 5 • 10     x + 50

——————————  =  ——————

    10           10  

Equation at the end of step  2  :

 (x + 50)    

 ———————— -  (x - 13)  = 0  

    10        

Step  3  :

Rewriting the whole as an Equivalent Fraction :

3.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  10  as the denominator :

             x - 13     (x - 13) • 10

   x - 13 =  ——————  =  —————————————

               1             10      

Adding fractions that have a common denominator :

3.2       Adding up the two equivalent fractions

(x+50) - ((x-13) • 10)     180 - 9x

——————————————————————  =  ————————

          10                  10    

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  180 - 9x  =   -9 • (x - 20)  

Equation at the end of step  4  :

 -9 • (x - 20)

 —————————————  = 0  

      10      

Step  5  :

When a fraction equals zero :

5.1    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:

 -9•(x-20)

 ————————— • 10 = 0 • 10

    10    

Now, on the left hand side, the  10  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  -9  •  (x-20)  = 0

Equations which are never true :

5.2      Solve :    -9   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

5.3      Solve  :    x-20 = 0  

Add  20  to both sides of the equation :  

x=20

does that make any sense? I know it's long, but it explains it.

Answer:

x = 20

I am not sure if you wanted the answer. Sorry!

Step-by-step explanation:

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

1/10 x + 5 = - 3x - 13 + 4x

Step 1: Simplify both sides of the equation.

1/10 x + 5 = - 3x - 13 + 4x

1/10 x + 5 = - 3x + - 13 + 4x

1/10 x + 5 = (<em>- 3x + 4x</em>) + (- 13)

1/10 x + 5 = <em>x</em> + - 13

1/10 x + 5 = x - 13

Step 2: Subtract x from both sides.

1/10 x + 5 - <em>x </em>= x - 13 - <em>x</em>

- 9/10 x + 5 = - 13

Step 3: Subtract 5 from both sides

- 9/10 x + 5 - <em>5</em> = - 13 - <em>5</em>

- 9/10 x = - 18

Step 4: Multiply both sides by 10/(- 9).

(<em>10/ - 9</em>) * (- 9/10 x) = (<em>01/ - 9</em>) * (- 18)

x = 20

Hope this helps!

Which is an equation of a line through (7,1) and perpendicular to y=-x+3
zysi [14]

Answer:

The answer is y=-1x+8 or you can write it this way y=-x+8 either way will work fine.

Step-by-step explanation:

y=mx+b

m=-1

y-y=m(x-x¹)

y-1=-1(x-7)

y-1=-1x+7

+1 +1

y=-x+8

I hope this helps:)

Answer ASAP. Please give correct answer. (Involves a bunch of circles and trig identities)
iren [92.7K]

Answer:

45.40

Step-by-step explanation:

First of all, the shape of rope is not a parabola but a catenary, and all catenaries are similar, defined by:

y=acoshxa

You just have to figure out where the origin is (see picture). The hight of the lowest point on the rope is 20 and the pole is 50 meters high. So the end point must be a+(50−20) above the x-axis. In other words (d/2,a+30) must be a point on the catenary:

a+30=acoshd2a(1)

The lenght of the catenary is given by the following formula (which can be proved easily):

s=asinhx2a−asinhx1a

where x1,x2 are x-cooridanates of ending points. In our case:

80=2asinhd2a

40=asinhd2a(2)

You have to solve the system of two equations, (1) and (2), with two unknowns (a,d). It's fairly straightforward.

Square (1) and (2) and subtract. You will get:

(a+30)2−402=a2

Calculate a from this equation, replace that value into (1) or (2) to evaluate d.

My calculation:

a=353≈11.67

d=703arccosh257≈45.40

Below are two parallel lines with a third line intersecting them.
andrew-mc [135]

Answer:

132 degrees

Step-by-step explanation:

One sit of the 48 degrees is 48 degrees, so that opposite will be the same. Add them up, get 96. There is a full 360 degrees circle, so get 360 and subtract 96 from it, to get 264 degrees. That is the top and bottom angle of the right side, so just divide it in two
