Answer:

Step-by-step explanation:

x = 1/4

y = -x = -1/4

The price of an item has dropped to $63 today. Yesterday it was $140. What was the percentage decrease?

den301095 [7]

Given:

a.) The price of an item has dropped to $63 today.

b.) Yesterday it was $140.

For us to be able to determine the percentage decrease, we will be using the following formula:

$\text{ Percentage Decrease = }\frac{\text{ Original Price - Present Price}}{\text{ Original Price}}\text{ x 100}$

We get,

Original Price = $140

Present Price = $63

$\text{ Percentage Decrease = }\frac{\text{ Original Price - Present Price}}{\text{ Original Price}}\text{ x 100}$ $\text{ = }\frac{\text{ 140 - 63}}{\text{ 140}}\text{ X 100}$ $\text{ = }\frac{77}{140}\text{ X 100}$ $\text{ = }0.55\text{ x 100}$ $\text{Percentage Decrease = }55\text{\%}$

Therefore, the decrease of the price in percentage is 55%.

Help urgently need help

Answer:

$y=\dfrac{8}{7}x - \dfrac{23}{7}$

Step-by-step explanation:

Rearranging the terms, we get $7y=8x-23$ . Dividing both sides by 7, we get $\dfrac{7y}{7} = \dfrac{8x-23}{7}$ , so $\boxed{y=\dfrac{8}{7}x - \dfrac{23}{7}}$

Solve for x -3(x-1)=3(4-x)-9

GuDViN [60]

Solving for x is easier if
First, remove the parenthesis.

-3(x-1) = 3(4-x)-9
-3x + 3 = 12 - 3x - 9

Next, group the numbers with x on the left side and the rest on the right side.

-3x + 3x = 12 - 9 - 3
0 = 0

So, x has no solution.
