Answer:

The answer is 11.

Step-by-step explanation:

Use PEMDAS

P - Parenthesis

E - Exponents

M - Mulitiplication

D - Divide

A - Add

S - Subtract

So, with that you learn that you solve whatever is in the parenthesis first.

(9 - 3) = 6

Now, divide 20 by 4 which equals 5.

So now the problem is now 6 + 5 which equals 11.

The answer is 11.

Adam exchanged British pounds for Swiss franc He changed £400 into 592 francs What was the exchange rate of British pounds to Sw

OLEGan [10]

Answer: 1 : 1.48

Step-by-step explanation:

Adam was able to change £400 into 592 francs which means that the British pound is stronger because it was able to buy more Swiss francs.

The exchange rate can be gotten using direct proportion:

400 : 592

1 : x

Cross multiply:

400x = 592

x = 592/400

x = 1.48

Exchange rate is:

= 1 : 1.48
