Answer: the old price for 1 liter is $0.3
Step-by-step explanation:
Let x represent the old price for 1 liter of petrol.
Last week a man bought 20 liters at the old price. This means that the total amount that the man paid for 20 liters is 20x.
The cost of petrol rises by 2 cents a liter. This means that the new price per liter is x + 2/100 = x + 0.02
This week he bought 10 liters at the new price. This means that the total amount that the man paid for 10 liters is
10(x + 0.02)
= 10x + 0.2
Altogether, the petrol costs $9.20. This means that
20x + 10x + 0.2 = 9.2
30x + 0.2 = 9.2
30x = 9.2 - 0.2
30x = 9
x = 9/30
x = 0.3
The total number of Games.....TNG=24
Sports Related Games...............SRG=06
Role Playing Games.....................RPG=18 (24-6)
The ratio of Role Playing Games to Total Number of Games=RPG:TNG
18:24
3:4 is the answer. A ratio is actually a concept related to Division. Here in 18:24 you can divide both sides by 6 to reach the answer 3:4.
I'm guessing it is 18. 18 decreased by nine equals nine so to me it makes sense.
Answer:
g(4) = -5, h(8)= 8, f(-2)= -7, g(-2)= 7
Step-by-step explanation:
It's pretty simple. The number in the parenthesis is the value of x.
Therefore, you look at the table, find the required function and the value of x that is given.
The number that is in the answers is the value of y.
