What number makes the sentence true?<br> 15 – 7 = 3+1
nasty-shy [4]

Answer:

4

Step-by-step explanation:

Although you didn't give me any answers to go with your problem, I am assuming that since 15-7 is 8, and 3 + 1 = 4, the answer should be 4. Now regarding if it is times, it would be x2. Because for times 2 would be 8. Overall the answer should be 4.

Solve for x: 3/4x+5/4=4x?
butalik [34]

Answer:

x = 5/13 = 0.385

Step-by-step explanation:

Step  1  :

           5

Simplify   —

           4

Equation at the end of step  1  :

   3         5    

 ((— • x) +  —) -  4x  = 0

   4         4    

Step  2  :

           3

Simplify   —

           4

Equation at the end of step  2  :

   3         5    

 ((— • x) +  —) -  4x  = 0

   4         4    

Step  3  :

Adding fractions which have a common denominator :

3.1       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:

3x + 5     3x + 5

——————  =  ——————

  4          4  

Equation at the end of step  3  :

 (3x + 5)    

 ———————— -  4x  = 0

    4        

Step  4  :

Rewriting the whole as an Equivalent Fraction :

4.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  4  as the denominator :

         4x     4x • 4

   4x =  ——  =  ——————

         1        4  

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 :

4.2       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:

(3x+5) - (4x • 4)     5 - 13x

—————————————————  =  ———————

        4                4  

Equation at the end of step  4  :

 5 - 13x

 ———————  = 0

    4  

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:

 5-13x

 ————— • 4 = 0 • 4

   4  

Now, on the left hand side, the  4  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  5-13x  = 0

Solving a Single Variable Equation :

5.2      Solve  :    -13x+5 = 0

Subtract  5  from both sides of the equation :

                     -13x = -5

Multiply both sides of the equation by (-1) :  13x = 5

Divide both sides of the equation by 13:

                    x = 5/13 = 0.385

One solution was found :

                  x = 5/13 = 0.385
