A jeweler had a fixed amount of gold to make bracelets and necklaces. The amount of gold in each bracelet is 5 grams and the amount of gold in each necklace is 20 grams. The jeweler made a total of 13 bracelets and necklaces using 185 grams of gold. Determine the number of bracelets made and the number of necklaces made.

the number of bracelets made and the number of necklaces made is 13 and 6 respectively

Step-by-step explanation:

The computation is shown below:

Let us assume the number of bracelets be x

And, the number of necklaces be y

now the equations are

5x + 20y = 185

Since the total number of bracelets is given i.e. 13

So

5(13) + 20y = 185

65 + 20y = 185

20y = 185 - 65

y = 120

y = 6

Hence, the number of bracelets made and the number of necklaces made is 13 and 6 respectively

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
