x=-3, y=1
Step-by-step explanation:
Given equations are:
2x-3y=-9 Eqn 1
x+y = - 2 Eqn 2
From eqn 2:
Putting x=-y-2 in eqn 1
Hence,
x=-3, y=1

The bag contains 6 tiles: 2 lettered and 4 numbered. The probability of drawing a number without looking is 2/3.
Probability is the ratio of the number of favorable outcomes and a total number of outcomes. it deals with finding out the likelihood of the occurrence of an event.
Given that,
The bag holds 6 tiles.
Among the tiles, 2 are lettered and 4 are numbered.
The task is to choose a tile from the bag without looking.
The bag contains a total of 6 tiles: 2 lettered and 4 numbered.
Therefore,
The probability of drawing a number can be calculated by dividing the number of numbered tiles by the total number of tiles.
Probability of drawing a number = (Number of numbered tiles) / (Total number of tiles)
Probability of drawing a number = 4 / 6
Simplifying this fraction, we get:
Probability of drawing a number = 2 / 3
Hence,
The probability of drawing a number from the bag is 2/3.
