This question is based on system of equations.The system of equations that is used to determine the number of bracelets made and the number of necklaces made is x + y = 13 and 8x + 24y = 168.

Given:

The amount of gold in each bracelet is 8 grams and the amount of gold in each necklace is 24 grams. The jeweler made a total of 13 bracelets and necklaces using 168 grams of gold.

According to the question,

Let x represent the number of bracelets and y represent the number of necklaces that the jeweler made.

The jeweler made a total of 13 bracelets. This means that

⇒ x + y = 13

It is given that, the amount of gold in each bracelet is 8 grams and in each necklace is 24 grams. The jeweler made a total of 13 bracelets and necklaces using 168 grams of gold. This means that,

⇒ 8x + 24y = 168

Therefore, the system of equations that is used to determine the number of bracelets made and the number of necklaces made is x + y = 13 and 8x + 24y = 168.

The system of equations that could be used to determine the number of bracelets made and the number of necklaces made is

x + y = 13

8x + 24y = 168

Step-by-step explanation:

Let x represent the number of bracelets that the jeweler made.

Let y represent the number of necklaces that the jeweler made.

The jeweler made a total of 13 bracelets. This means that

x + y = 13

The amount of gold in each bracelet is 8 grams and the amount of gold in each necklace is 24 grams. The jeweler made a total of 13 bracelets and necklaces using 168 grams of gold. This means that

8x + 24y = 168

Answer from: Quest

the dimensions are: $(2b+-+1)$

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

$v(b)=50b^3+75b^2-2b-3$

we factor to obtain;

$v(b)=(2b+3)(25b^2-1)$

we rewrite the rightmost factor to obtain;

$v(b)=(2b+)^2-1^2)$

recall that:

$a^2-b^2=(a+b)(a-b)$

we apply difference of two squares formula to obtain;

$v(b)=(2b+3)(5b-1)(5b+1$

hence the dimensions are

$(2b+-+1)$
