3. Reduction

For example,
11x - 3y = 69
-3x + 3y = 3
___________
8x + 0y = 72 => x = 72/8 => x = 9 => -27 + 3y = 3 => 3y = 30 => y = 30/3 => y = 10.

sam filled 6 glasses with six glasses with two 2/3 liters of juice in each glass. how many liters of juice did he use ?

Tcecarenko [31]

So, Sam filled 6 glasses with 2/3 liters. We want to find out how many liters of juice he used.

To find this out we do 6 * 2/3.
(2/3+2/3+2/3+2/3+2/3+2/3)
(12/3) (Denominator stays the same)
12/3 = 4
Sam uses 4 liters.

Hope this helps you! (:

In a game of cornhole, Sasha tossed a bean bag and it landed at the edge of the hole. The hole can be represented by the equatio

Nitella [24]

In the game of cornhole, when Sasha tossed a bean bag to the edge of the hole, in which the equations of the hole and bean bag's path are x² + y² = 5 and y = 0.5x² + 1.5x - 4, respectively, she could have tossed her bean bag to the points (1, -2) or (2, 1).

To find the points in which she could have tossed her bean bag, we need to intersect the two equations of the function as follows.

The equation for the hole

$x^{2} + y^{2} = 5$ (1)
