20 litres = 18 pounds

20/20 litres = 18/20 pounds ... divide both sides by 20

1 litre = 0.9 pounds

1 litre of petrol costs £ 0.9

X^2 +2x +10 = 0

D = 4 -40 = - 36 

x_1,2 = (-2 +/- sqrt(-36))/2 = (-2 +/- 6i)/2 = 2(-1 +/- 3i)/2 = -1 +/- 3i 

x_1,2 = -1 +/- 3i   or more understandably 

x_1 = -1 -3i and x_2 = -1 +3i

hope this will help you

X+6 /3 = 2+x-2/5

We can treat this problem like you regularly subtract fractions. First find the common denominator, which is 15.

So:

5(x+6)/15 = 30/15 + 3(x-2)/15

(5x+6)/15 - (30/15) - (3x - 6)/15


As you already know the answer, I'm assuming you can do the rest.

Hope this helps!

I don't really understand these because our teachers expect me to know this when she didn't teach us this.

First, find the percentage of the price after the sale occures
percent = 100% - 20%
percent = 80%

We need to find the price for the pairs with the percentage above
new price = percentage of new price/percentage of old price × old price
new price = 80%/100% × 55
new price = 4/5 × 55
new price = 44
The new price is $44

Now we estimate how much the tax
tax = 6% × 44
tax = 6/100 × 44
tax = 2.64

Calculate how much Josie will pay
pay = new price + tax
pay = 44 + 2.64
pay = 46.64

Josie will pay $46.64
