$y45 \sqrt{15}$
​

Answer 1

Answer: can u pls mark me brainliest pls

(15/100)=y-(45/100)  

One solution was found :

                  y = 3/5 = 0.600

Reformatting the input :

Changes made to your input should not affect the solution:

(1): ".45" was replaced by "(45/100)". 2 more similar replacement(s)

Rearrange:

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

                    (15/100)-(y-(45/100))=0  

Step by step solution :

Step  1  :

            9

Simplify   ——

           20

Equation at the end of step  1  :

  15           9

 ——— -  (y -  ——)  = 0  

 100          20

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  20  as the denominator :

         y     y • 20

    y =  —  =  ——————

         1       20  

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:

y • 20 - (9)     20y - 9

————————————  =  ———————

     20            20    

Equation at the end of step  2  :

  15    (20y - 9)

 ——— -  —————————  = 0  

 100       20    

Step  3  :

            3

Simplify   ——

           20

Equation at the end of step  3  :

  3    (20y - 9)

 —— -  —————————  = 0  

 20       20    

Step  4  :

Adding fractions which have a common denominator :

4.1       Adding fractions which 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 - ((20y-9))     12 - 20y

—————————————  =  ————————

     20              20    

Step  5  :

Pulling out like terms :

5.1     Pull out like factors :

  12 - 20y  =   -4 • (5y - 3)  

Equation at the end of step  5  :

 -4 • (5y - 3)

 —————————————  = 0  

      20      

Step  6  :

When a fraction equals zero :

6.1    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:

 -4•(5y-3)

 ————————— • 20 = 0 • 20

    20    

Now, on the left hand side, the  20  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  -4  •  (5y-3)  = 0

Equations which are never true :

6.2      Solve :    -4   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

6.3      Solve  :    5y-3 = 0  

Add  3  to both sides of the equation :  

                     5y = 3

Divide both sides of the equation by 5:

                    y = 3/5 = 0.600

One solution was found :

                  y = 3/5 = 0.600
