A sofa regularly rells for $800. The sale price is $600

sveta [45]

Because the sofa usually sells for $800, we know that's 100% of the price.

100% = $800

Let's find 1%.

1% = $800/100

1% = $8

Next, multiply $8 by 75 to find the percent of the sofas price when it's $600.

75% = $600

We now know that $600 is 75% of the sofas original price.

100% - 75% = 25%

The percent of decrease I'm the sofas sale price is 25%.

Hope I got that right, the question was worded a little strangley so I wasn't quite sure what you were asking :)

The rectangle below has an area of 1 8 x 3 18x 3 square meters and a length of 2 x 2 2x 2 meters.

Answer:

$\text{The width of rectangle}=9x\text{ meters}$

Step-by-step explanation:

We have been given that the rectangle has an area of $18x^3$ square meters and a length of $2x^{2}$ . We are asked to find the width of rectangle.

Since we know that area of a rectangle is width times length of the rectangle, so we can find width of our given rectangle by dividing given area by length of rectangle.

$\text{Area of rectangle}=\text{Width of rectangle *Length of the rectangle}$

$\frac{\text{Area of rectangle}}{\text{Length of rectangle}}=\frac{\text{Width of rectangle *Length of the rectangle}}{\text{Legth of rectangle}}$

$\text{The width of rectangle}=\frac{\text{Area of rectangle}}{\text{Length of rectangle}}$

Upon substituting our given values in above formula we will get,

$\text{The width of rectangle}=\frac{18x^3\text{ meter}^2}{2x^2\text{ meters}}$

$\text{The width of rectangle}=\frac{9x^3\text{ meters}}{x^2}$

Using exponent rule for quotient $\frac{a^m}{a^n}=a^{m-n}$ we will get,

$\text{The width of rectangle}=9x^{3-2}\text{ meters}$

$\text{The width of rectangle}=9x^{1}\text{ meters}=9x\text{ meters}$

Therefore, width of our given rectangle will be 9x meters.

Scilla [17]

Ariel deposited 100$ into a bank account. Each Friday she will withdraw 10% of the money in the account to spend. Ariel thinks her account will be empty after 10 withdrawals. Do you agree? Explain
OK, my initial answer is YES. I agree.
Why? Let me show you the solutions
=> 100 dollars = the money of Ariel in the bank
=> 10% = he withdraw every Friday
10% of 100 is:
=> 100 / 10 = 10 dollars
Thus, after his 10th withdrawal, his account will be empty.

2x + 3y = 7 3x + 2y = 8

Kipish [7]

Answer:

$\boxed{\sf \ \ \ x=2, \ \ y =1 \ \ \ }$

Step-by-step explanation:

Hello,

Pls post the full question next time so that we can make sure what is expected.

I assume that you want to solve for (x,y)

(1) 2x + 3y = 7

(2) 3x + 2y = 8

2*(2)-3*(1) gives

2*3x + 2*2y - 3*2x - 3*3y = 2*8 - 3*7 = 16 - 21 = -5

6x - 6x + 4y -9y = -5

-5y=-5

y = 1

and we can replace in (1)

2x + 3*1 = 7

2x = 7 - 3 = 4

x = 2

hope this helps
