Y^2 + 5Y + 2Y^2 - 4Y= ?
add up the like terms
(Y^2 + 2Y^2) + (5Y - 4Y)=
=3Y^2 + 3Y
First you are want to think of what two numbers will give you 72. It gives you 6, so you need to think of 6 times what will give you 72 (which is 12). Next you want to break down the 12, and you do the exact same thing you did with the 72. It gives you the number 3 so you need to find out 3 times what equals 12 (which is 4). Then you break down the 4 the same way. You have to do that to the 6 as well.
You continue to break down numbers until you can’t anymore.
Let hot dogs = X
So then soda would be 2x ( two times as much).
Now you have:
X + 2X = 162
Simplify:
3x = 162
Divide both sides by 3:
X =162 / 3
X = 54
2x = 54 *2 = 108
108 sodas and 54 hot dogs were sold.
Answer:
1:3 is an example and for every two boy there are 5 girls is another example
Edited: I go out Five times as much as My sister does. My sister goes out only 3 times. Which is 15:1
I see 5 blue cars for every 6 red cars. Which is 5:6
