Yes rational expression and its simplified forms are equivalent.

Rational expression are those that contain fractions.

Example:
25/50 is a rational expression but it is not yet in its simplest form.

25/50 ⇒ 5/10 ⇒ 1/2

1/2 is the simplest form of 25/50.

They are equivalent:

1/2 = 25/50
1*50 = 2*25
50 = 50

or
1/2 = 0.50
25/50 = 0.50

The ratio of money in Terry's bank account to Faye's bank account was 3:7.

igor_vitrenko [27]

Answer:

£390

Step-by-step explanation:

The ratio of money in bank:

Terry : Faye

3 : 7

Terry put £220 in his account

Faye withdrew £300 from her account

Unknown:

Initial amount Terry had = ?

Solution:

Let the real amount terry has = 3x

Faye will have = 7x

Now;

3x + 220 = 7x -300

Solving this equation:

3x + 220 = 7x -300

3x - 7x = -300 - 220

-4x = - 520

4x = 520

x = 130

Originally, Terry has 3x = 3 x 130 = £390

cos θ = $\frac{-4\sqrt{65} }{65}$ , sin θ = $\frac{-7\sqrt{65} }{65}$ , cot θ = 4/7, sec θ = $\frac{-\sqrt{65} }{4}$ , cosec θ = $\frac{-\sqrt{65} }{7}$
