Rearrange the terms
5 - x = 8
-x + 5 = 8

Subtract 5 from both sides
-x + 5 = 8
-x+5-5 = 8-5

subtract the numbers ( simplify )
-x = 3

divide both sides
-x = 3
-x/-1 = 3/-1

simplify
x = 3/-1
x = -3

So therefore, your answer is x = -3

In a particular month, Ezhil spent one-fifth of her salary on shopping. Two-fifth of the remaining she gave to her sister. If sh

Oxana [17]

Answer:

$Salary = Rs23000$

Step-by-step explanation:

Given

$Shopping = \frac{1}{5}$

$Sister = \frac{2}{5}R$

$Left over = Rs11,040$

Required

Her salary in that month

Given that she spent $\frac{1}{5}$ of her salary on shopping, this implies that she has $\frac{4}{5}$ of her salary left

From what's left, she gave her sister $\frac{2}{5}$

This means she gave her sister $\frac{2}{5} * \frac{4}{5}$

Sister = $\frac{8}{25}$

Calculating a fraction of what's left

$Left over = 1 -Shopping - Sister$

$Left over = 1 - \frac{1}{5}- \frac{8}{25}$

$Left over = \frac{25 - 5 - 8}{25}$

$Left over = \frac{12}{25}$

Recall that she has Rs11,040

This means that

$\frac{12}{25} of Salary = Rs11,040$

Multiply both sides by $\frac{25}{12}$

$\frac{12}{25} * \frac{25}{12} * Salary = Rs11,040 * \frac{25}{12}$

$Salary = Rs11,040 * \frac{25}{12}$

$Salary = \frac{Rs276000}{12}$

$Salary = Rs23000$

Hence, her salary for that month was Rs23000

Like bought 15 boos six books each cost $7 four of the books each cost $5 the rest of the books each cost $3 how many do all the

Gekata [30.6K]

Answer:

The total combined cost of 15 books is $77.

Step-by-step explanation:

Here, the total number of books purchased = 15

The cost of books = $7 for 6 books

So, the cost of six books = 6 x ( cost of 1 book) = 6 x ($7) = $42

⇒Out of 15 books, the cost of 6 books = $42 .... (1)

The cost of books = $5 for 4 books

So, the cost offour books = 4 x ( cost of 1 book) = 4 x ($5) = $20

⇒Out of 15 books, the cost of 4 books = $20 .... (2)

Now, the left books are at cost $3 each book.

The number of left books = 15 - ( 6+4) = 15 - 10 = 5

So, the cost of books = $3 for 5 books

So, the cost of five books = 5 x ( cost of 1 book) = 5 x ($3) = $15

⇒Out of 15 books, the cost of 5 books = $15 .... (3)

Now, to get the total price of 15 books add (1) + (2) + (3), we get:

$42 + $20 + $15 = $77

Hence, the total combined cost of 15 books is $77.
