Answer:
Step-by-step explanation:
Let
y ----> the number of rides
x ---> the number of games
we know that
The number of rides multiplied by $1 plus the number of games multiplied by $0.25 must be equal to $12 (the dollar amount Koran is spending)
so
The equation that represent this situation is
The perimeter would be about 34.4 because if you choose the bottom side to be ten, by multiplying 35 by 2 to get 70 you can divide by 10 to get 7. Since you know the height and width, you can use pythagorean theorem, a^2 + b^2 = c^2. Plug in the numbers you have 10^2+7^2=c^2. c^2=149, so if you square root 149 you will get a irrational number but when rounded you get 12.2- so that is one side multiply by 2 and get 24.4- and add 10 to get 34.4
If she read 20 in half an hour how many can she read in 1 hour=40
so, that gets you 120 the answer is she can read 120 pages in 3 hours
It is; Five million Six hundred seventy four thousand eight hundred ninety. As simple as that.
