Liam thinks of a number.

1 answer:

7 0

so say the number he's thinking of is n, write n down, then he multiplies it by 5 which is 5n then he subtracts 60 from 5n, which is 5n-60, the question states that the answer "5n-60" is equal to the number he started with which is n, so you setup 5n-60=n and solve for n.

BARSIC [14]

Answer:

You should receive 286.0821056 US dollars

Step-by-step explanation:

* Lets explain how to solve the problem

- The exchange rate is USD/EURO 0.6991

- That means 1 USD = 0.6991 EURO

- You have 200 EURO

- You want to convert them to US dollars

∵ 1 dollars = 0.6991 euro

USD : EURO

1 : 0.6991

x : 200

∴ $\frac{1}{0.6991}=\frac{x}{200}$

- By using cross multiplication

∴ 0.6991 x = 200

- Divide both sides by 0.6991

∴ x = 286.0821056

∵ x represents the amount of US dollars

∴ <em>You should receive 286.0821056 US dollars</em>
