Given the ABC DEF find the value of x and y

Artemon [7]

Answer: x = 7.2, y = 7.5

<u>Step-by-step explanation:</u>

Similar triangles have the same proportions.

Since ABC ≅ DEF, then $\dfrac{AB}{DE}=\dfrac{BC}{EF}=\dfrac{AC}{DF}$

<u>Let's solve for x:</u>

$\dfrac{BC}{EF}=\dfrac{AC}{DF}$

⇒ $\dfrac{5}{4}=\dfrac{9}{x}$

⇒ $5(x)=4(9)$

⇒ $x = \dfrac{4(9)}{5}$

⇒ $x = \dfrac{36}{5}$

⇒ $x = 7.2$

<u>Let's solve for y:</u>

$\dfrac{BC}{EF}=\dfrac{AB}{DE}$

⇒ $\dfrac{5}{4}=\dfrac{y}{6}$

⇒ $5(6)=4(y)$

⇒ $\dfrac{5(6)}{4}=y$

⇒ $\dfrac{30}{4}=y$

⇒ $7.5=y$

The cost in dollars to print n books is 500 + 10n. How many books are printed for a cost of $15 000?

12345 [234]

N= the # of books
So you're trying to find n and you have the cost for the printed books, which is 15,000, so you would set up your equation like this:
15,000=500+10n
Subtract 500 from each side
14850=10n
Divide by 10
n=1,485 books are printed
