HELP!!!!!!!!!!!!!!!!!!

padilas [110]

First, factor each expression by finding two terms whose product is equal to the c term and sum is equal to the b term.

x^2-x+6 --> (x-3)(x+2)

x^2-4 --> (x+2) (x-2)

Next, cancel the terms that are equal on the top and bottom.

You are left with the answer of: $\frac{x-3}{x-2}$

Hope this helps!!

While conducting an inventory in their bicycle shop, the owner noticed the number of bicycles is 2 fewer than 10 times the numbe

mr Goodwill [35]

Answer:

The number of bicycles in the store is $178\ bicycles$

Step-by-step explanation:

Let

x------> the number of bicycles

y-----> the number of tricycles

we know that

The bicycles has two wheels and the tricycles has three wheels

$2x+3y=410$ ------> equation A

$x=10y-2$ ------> equation B

substitute equation B in equation A and solve for y

$2(10y-2)+3y=410$

$20y-4+3y=410$

$23y=414$

$y=18\ tricycles$

Find the value of x

$x=10(18)-2=178\ bicycles$
