Solve -5 + w/3 = 1<br> 12<br> -12<br> 2<br> -2
Mumz [18]

Answer:

w = 12

Step-by-step explanation:

Step  1  :

           w

Simplify   —

           3

Equation at the end of step  1  :

        w    

 (-5 +  —) -  -1  = 0

        3    

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Adding a fraction to a whole

Rewrite the whole as a fraction using  3  as the denominator :

          -5     -5 • 3

    -5 =  ——  =  ——————

          1        3  

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:

-5 • 3 + w     w - 15

——————————  =  ——————

    3            3  

Equation at the end of step  2  :

 (w - 15)    

 ———————— -  -1  = 0

    3        

Step  3  :

Rewriting the whole as an Equivalent Fraction :

3.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  3  as the denominator :

         -1     -1 • 3

   -1 =  ——  =  ——————

         1        3  

Adding fractions that have a common denominator :

3.2       Adding up the two equivalent fractions

(w-15) - (-1 • 3)     w - 12

—————————————————  =  ——————

        3               3  

Equation at the end of step  3  :

 w - 12

 ——————  = 0

   3  

Step  4  :

When a fraction equals zero :

4.1    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:

 w-12

 ———— • 3 = 0 • 3

  3  

Now, on the left hand side, the  3  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  w-12  = 0

Solving a Single Variable Equation :

4.2      Solve  :    w-12 = 0

Add  12  to both sides of the equation :

                     w = 12

One solution was found :

                  w = 12

Answer:

Multiply input by 4.

Step-by-step explanation:

So, all we have to do is find the difference between the input/output.

So for the first one.

4y=1x

Divde both sides:

1y=1/4x

Next we have 16y=4x

Divide both sides:

1y=1/4x

Ok, so we now know that y is 1/4x

Or in otherwords, 4x is 1y.

Remember x is input, and y is output.

So we can think of this as the input times 4 equals the output.

This seems to be the second answer.

Hope this helps!

The number represented by x is less than 7 and is evenly divisible by both 0.6 and 2.4
svetoff [14.1K]
2.4<7
2.4 / 0.6 = 4
2.4 / 2.4 = 1

4.8<7
4.8 / 0.6 = 8
4.8 / 2.4 = 2
