Answer:
it should be 7 fasho
Step-by-step explanation:
Answer:
We suppose that a is the old price in cents
the total cost of 9.20 $ equals 920 cents
so we have 20 liters bought with the old price (a) and 10 liters with the new price (a + 2). This is translated into this equation where a is the old price therefore our quest to be answered
20 xa + 10 x (a + 2) = 920 (cents)
20 xa + 10 xa + 20 = 920
30 xa + 20 = 920
30 xa = 920 - 20
30 xa = 900
a = 900: 30
a = 30 (cents)
therefore the old price for 1 liter of petrol is 30 cents

Step-by-step explanation:
Hi, thank you for posting your question here in Brainly.
Celsius and Fahrenheit are units of temperature, and they can be converted using a formula.
F = C*1.8 + 32
For example, 30°C is
F= 30*1.8 + 32
F = 86°F
Or an easier way to remember without memorizing the formula is by remembering the normal boiling point of water which is 100°C = 212°F.
For the first one, the answer is yes.
2. A.-1.
i hope this helps.
