When -3 is squared it becomes 9 then -3x5 is -15 so put that back into the equation 9-15+9= 4
Answer:
£152
Step-by-step explanation:
Solution:
Find out how much is 1/3 of 255 coins:
255 x 1/3 = 85
Since you know how many 50p and £1 coins there are, the remaining of the coins after the 50p and £1 get deducted from the total coins.
255 - 85 - 110 = 60
There are 60 20p coins, 85 £1 coins and 110 50p coins.
Find out the total value by calculating them all altogether.
60 x 20p = 1200
85 x 100p which is £1 = 8500
110 x 50p = 5500
I did them separately so that it wouldn't be so confusing.
Convert them into £, then after that add them up.
£12 + £85 + £55 = £152
If you meant to write 
then the statement is true.
As a more concrete example, something like 
would be read out as "log base 3 of 81 is equal to 4".
6 pages per second so the equals 4 that equals plus 2 equals 6
