Problem page the price of a notebook has dropped to $3.20 today. Yesterday's price was $3.45 . Find the percentage decrease. Rou

Anna11 [10]

Yesterday's price of notebook = $3.45

Today's price of notebook = $3.20

We have to determine the percentage decrease in the cost of notebook.

Percentage decrease = (Decrease $\div$ Old price) $\times 100$

So, percentage decrease = $\frac{3.45-3.20}{3.45} \times 100$

= $\frac{0.25}{3.45} \times 100$

= 7.246%

= 7.25%

Therefore, there is 7.25% of decrease in the cost of the notebook.

What is x/13-5=25/26

Juliette [100K]

$\frac{x}{13} -5=\frac{25}{26}$ Add 5 on both sides

$\frac{x}{13}=\frac{25}{26}+5$ Make the denominators the same

$\frac{x}{13}=\frac{25}{26}+\frac{130}{26}$

$\frac{x}{13}=\frac{155}{26}$ Multiply 13 on both sides

$(13)\frac{x}{13}=(13)\frac{155}{26}$

$x=\frac{2015}{26}$

$x=\frac{155}{2}$

Describe how you would graph a figure that is translated by (x - 4,4+2).

atroni [7]

Answer:

see explanation

Step-by-step explanation:

Given the translation rule

(x, y ) → (x - 4, y + 2 )

This means subtract 4 from the original x- coordinate and add 2 to the original y- coordinate, that is

a point (4 , - 4 ) → (4 - 4, - 4 + 2 ) → (0, - 2 )
