b = h

c = 10 cm

Plug in the values

3² + h² = 10²

2. Rich wrote a novel that sells for n dollars each. He received a bonus of $50,000 to sign the

Yuki888 [10]

The equation which represent total amount of income he earns from selling book is, $A=50000+\frac{109}{100}bn$

Since, Selling price of one novel is n dollars

So, selling price of b books is, $n*b=nb$

Since, he receives 9% commission on each book sale.

So, total commission he receives on selling of b books is,

$nb*\frac{9}{100}=\frac{9}{100}nb$

And also he received a bonus of $50,000 to sign the contract to write the book,

So, total amount of income he earns is represented by A,

$A=50000+bn+\frac{9}{100}bn\\\\A=50000+\frac{109}{100}bn$

Answer:

x=5

Step-by-step explanation:

Set the 2 equations equal to each other and solve for x.

11x-28=7x-8

add 28 to both sides (-8+28=20)

11x=7x+20

subtract 7x from both sides (11x-7x=4x)

4x=20

divide both sides by 4 to isolate x (20/4=5)

x=5
