In order to join a flying club,there is a $200 annual fee and $20 a month fee to maintain the flying club runaway.Write an equat
Fudgin [204]

Answer:

The equation modelling the situation is T=200+20m.

After <u>10 months</u> the cost would be $400.

Step-by-step explanation:

Given:

Annual Fee of flying club = $200

Monthly fee = $20

We need to write an equation for total cost.

Solution:

Let the number of months be denoted 'm'

Let Total cost be denoted by 'T'

Now we can say that:

Total cost is equal to sum of Annual Fee of flying club plus Monthly fee multiplied by number of months.

framing in equation form we get;

T=200+20m

Hence The equation modelling the situation is T=200+20m.

Now given:

We need to find the number of months when total cost will be $400

So we will substitute T= 400 in above equation.

200+20m=400

Subtracting both side by 200 we get;

200+20m-200=400-200\\\\20m=200

Dividing both side by 20 we get;

\frac{20m}{20}=\frac{200}{20}\\\\m=10 \ months

Hence After <u>10 months</u> the cost would be $400.

What is the answer to the equation x squared minus 2x equals 15.
anzhelika [568]

Answer:

x = 5 \\ x =  - 3

Step-by-step explanation:

{x}^{2}  - 2x = 15 \\  {x}^{2}  - 2x - 15 = 0 \\  {x}^{2}   + 3x - 5x - 15 = 0 \\ x(x + 3) - 5(x + 3) = 0 \\ (x - 5)(x + 3) = 0 \\ x - 5 = 0 \:  \:  \:  \:  \: or \:  \:  \:  \: x + 3 = 0 \\ x = 5 \:  \:  \:  \: or \:  \:  \:  \:  \:  \: x =  - 3
