16. At the mall, a pair of jeans cost $44 and a pair of earring cost $12. You spend a total of $80
sergij07 [2.7K]

There are 3 pairs of earrings that you bought in addition to the jeans. Forming an equation with the given values helps to find the required value.

<h3>How to write an equation for the given information?</h3>

It is given that,

A pair of jeans cost = $44

A pair of earrings cost = $12

you spent a total of $80 before taxes.

So, the equation for the given data is,

$80 = $44 + $12x

Where x is the number of pairs of earrings.

<h3>Calculation:</h3>

Simplifying the obtained equation:

$80 = $44 + $12x

⇒ 12x = 80 - 44

⇒ 12x = 36

⇒ x = 36/12

∴ x = 3

Thus, you can buy three pairs of earrings at the mall in addition to the jeans.

marta [7]

Answer:

x=2√5/5

x=-2√5/5

Step-by-step explanation:

13√(2√5/5)^2-(2√5/5)^4+9√(2√5/5)^2+(2√5/5)^4=16

13√(4×5/25)-(16×25/625)+9√(4×5/25)+(16×25/625)

13√(4/5)-(16/25)+9√(4/5)+(16/25)

13√(4/25)+9√(36/25)

13×2/5+9×6/5

26/5+54/5

16=16 (proven)

11. The length of a rectangle is three times its width. The perimeter of the
Elenna [48]

Answer: The length of the rectangle is 37.5 inches and the width is 12.5 inches

Step-by-step explanation: The dimensions of the rectangle is not given but we have clues given. The length is given as three times it’s width which means if the width is W, then the length would be given as 3W (three times the width). Also the perimeter is given as 100 inches and the formula for the perimeter is;

Perimeter = 2(L + W)

We can now insert the known values as follows;

100 = 2(3W + W)

100 = 2(4W)

100 = 8W

Divide both sides of the equation by 8

12.5 = W

Having calculated the width as 12.5 inches, the length now becomes

L = 3W

L = 3 x 12.5

L = 37.5

Hence the length is 37.5 inches and the width is 12.5 inches
