Answer:
£135
Step-by-step explanation:
Original price = 100%
Percentage increase = 20%
New price = 100% + 20% = 120%
If 120% = £162
What about 100% = ?

= £135
It will take the seal 6.5 hours to swim 52 miles.
Answer:
4
Step-by-step explanation:
Simplify x and y by rationalising the denominator of both
To rationalise the denominator multiply the numerator/ denominator by the conjugate of the denominator.
The conjugate of 2 + 
is 2 -
The conjugate of 2 - is 2 +
x = 
= 
= 2 -
y = 
= 
= 2 +
Thus
x + y = 2 - + 2 + = 4
First you subtract 5 and 2. Which is 3. Then multiply 3 by 4. Which is 12. Then divde 12 by 2. You get 6. Then 6 plus 4 is 10. The answer is 10
