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

A. y:24=6:y<br><br> Can someone please help me

Nikolay [14]

Answer:

y = ± 12

Step-by-step explanation:

Given

y : 24 = 6 : y, or in fraction form

$\frac{y}{24}$ = $\frac{6}{y}$ ( cross- multiply )

y² = 144 ( take the square root of both sides )

y = ± $\sqrt{144}$ = ± 12
