To solve this problem you must apply the proccedure shown below:

 1. You have that:

 - He sales 13 gold rings and 18 silver rings in 9405 euros.
<span> - The cost of the silver ring is three times the cost of the gold ring.

 2. Keeping the information above on mind, you have the following system of equations:

 x: the gold ring.
 y: the silver ring.

 x+y=</span>9405
<span> x=3y

 3. Then, you have:

 (3y)+y=9405
 y=9405/4
 y=2351.23 euros

 x=3y
 x=3(</span>2351.23)
<span> x=7053.75 euros

Answer:

x=4.

Step-by-step explanation:

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

5/15=x/ x+8

Step 1: Cross-multiply.

5/15=x/ x+8

5*(x+8)=x*(15)

5x+40=15x

Step 2: Subtract 15x from both sides.

5x+40−15x=15x−15x

−10x+40=0

Step 3: Subtract 40 from both sides.

−10x+40−40=0−40

−10x=−40

Step 4: Divide both sides by -10.

−10x−10=−40−10

Then your answer will be x=4.

Express the recurring decimal 0.042 as a fraction in its simplest form.
rodikova [14]

Answer:

7/165

Step-by-step explanation:

This is a mixed recurring decimal (the zero is not repeating)

We take number after the decimal point     042

then we subtract  the non repeating.In this case is 0 so we not subtract anything

This will be the numerator  42

Now ,the denominator:

For each repeating decimal we write a 9 (in this case 2 nines)

For each non repeating decimal we write a zero

Denominator is 990

42/990  =  7/165

7:165 = 0.0424242......
