Answer 1: $y = 35x + 50$

Answer 2: will

Answer 3: $10

Step-by-step explanation:

Equation: $y = 35x + 50$

Registration fee is one time, so you just add to it.

You have to pay each time you go to a session, so x will be the amount of sessions, 35 will be the price of each session.

You can plug in the 8 to the equation, then solve for y:

$y = 35(8) + 50\\y = 280 + 50\\y = 330$

They will be able to pay for it because: $330 < 340$

They will have $10 left because:

$340 - 330 = 10$

340 is how much on the card and 330 is how much the 8 lessons (in total) cost.

Answer:

$\large\boxed{x\approx56.44}$

$\large\text{It's close to 55.0}$

Step-by-step explanation:

$\tan12^o\approx0.2126\\\\\tan12^o=\dfrac{12}{x}\to\dfrac{12}{x}=0.2126\qquad\text{convert the decimal to the fraction}\\\\\dfrac{12}{x}=\dfrac{2126}{10000}\qquad\text{cross multiply}\\\\2126x=120000\qquad\text{divide both sides by 2126}\\\\x=\dfrac{120000}{2126}\\\\x\approx56.44$
