one half the cost of a dress decreased by $12 is the same as 2/5 the cost of a dress. What is the cost of the dress?

guajiro [1.7K]

Answer:

$120

Step-by-step explanation:

Let the cost of the dress be "c"

ONE HALF the cost DECREASED by 12, can be written as:

$\frac{1}{2}c-12$

2/5th the cost of dress, can be written as:

$\frac{2}{5}c$

Now, we equate both parts and solve for c to get cost of dress. Shown below:

$\frac{1}{2}c-12=\frac{2}{5}c\\\frac{1}{2}c-\frac{2}{5}c=12\\\frac{5-4}{10}c=12\\\frac{1}{10}c=12\\c=\frac{12}{\frac{1}{10}}\\c=12*10\\c=120$

Thus,

The ccost of the dress is $120

In equilateral triangles STU:

Len [333]

<h3>Answer: B) 39</h3>

==========================================================

Explanation:

Equilateral triangles have three equal sides, ie the sides are all the same length.

Let's set sides ST and TU equal to each other and solve for x

7x-10 = 2x+25

7x-2x = 25+10

5x = 35

x = 35/5

x = 7

Then we use this to compute each side

ST = 7x-10 = 7*7-10 = 49-10 = 39
TU = 2x+25 = 2*7+25 = 14+25 = 39
US = x^2 - 10 = 7^2 - 10 = 49-10 = 39

Each side is 39 units long, so this confirms we have the correct answer.

In a box of chocolates, 1/5 of the chocolates contain nuts.

uysha [10]

Answer:

<em>1:4</em>

Step-by-step explanation:

<u>Ratios and Fractions</u>

It's given 1/5 of the chocolates in a box contain nuts. The rest do not contain nuts. The portion that does not contain nuts is:

$1 - \frac{1}{5}=\frac{4}{5}$

We need to calculate the ratio of the number of chocolates that contain nuts to the number of chocolates that do not contain nuts.

This can be done by dividing 1/5 by 4/5:

$\displaystyle \frac{\frac{1}{5}}{\frac{4}{5}}$

Operating:

$\displaystyle \frac{1}{5}\cdot\frac{5}{4}=\frac{1}{4}$

Expressing it as a ratio: 1:4
