y=12
Step-by-step explanation:
Use order of operations. Subtract 18 from both sides and the divide by 2.
2y+18 -18=42-18

y=12
The cost is £79.76. Since the car covers 560 miles and 34.5 miles is travelled by one gallon. So, dividing 560 by 34.5 we get 16.23. Since 1 gallon is 4.55 litres, 16.23 gallons is 73.8465. Now the cost of petrol is £1.08 per litre. So, multiplying 73.8465 by £1.08 we have £79.76
So First of all we need to know how to find the area of a circle.
Assuming that the apple pie is the shape of a circle
The formula for area is

Well we know that the radius = 3.14
And we know that
= 3.14 as well.
All we have to do is multiply..
3.14 x
= 30.95
So the area of the pie is 30.95 in
Good Luck! :)
