Answer:

  7

 ————

 15x2

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (4 • (x2))      7y  

 —————————— • ————————

     5y       (22•3x4)

Step  2  :

              7y  

Simplify   ————————

           (22•3x4)

Equation at the end of step  2  :

 (4 • (x2))    7y

 —————————— • ————

     5y       12x4

Step  3  :

Equation at the end of step  3  :

 22x2    7y

 ———— • ————

  5y    12x4

Step  4  :

           22x2

Simplify   ————

            5y

Equation at the end of step  4  :

 4x2    7y

 ——— • ————

 5y    12x4

Step  5  :

Dividing exponential expressions :

5.1    x2 divided by x4 = x(2 - 4) = x(-2) = 1/x2

Canceling Out :

5.2    Canceling out y as it appears on both sides of the fraction line

Final result :

   7

 ————

 15x2

Marcia sells bracelets. She sells each one for $1.50. This year she spent $32.76 on supplies. At the end of the year, she made $
Marianna [84]

Answer:

$1.5b - $32.76 = $292.74

Step-by-step explanation:

Profit = total revenue - total cost

total revenue = price per unit x total unit of bracelet sold

total revenue = $1.50  x b = $1.50b

b = total units of bracelets sold

total cost = $32.76

$1.5b - $32.76 = $292.74

Write x as a logarithm in the following: 10^x=7
pochemuha

Answer:

x = log 7

Step-by-step explanation:

10^x=7

Take the log base 10 on each side

log10 (10^x)=log10 (7)

We dont need to write the 10, it is implied

log(10^x)=log (7)

The exponent  goes out front since log a^b = b log a

x log 10 = log 7

log 10 = 1 since the base is 10 log10(10) =1

x = log 7
