Answer:
Given:
x-y=-4
2x+y=4
Step-by-step explanation:
x-y=-4
2x+y=4
add both the equation, we get
⇒ x-y=-4
2x+y=4
⇒3x=-4+4
⇒3x=0
⇒x=0
∴ to find the value of y, put the value of x in any one equation
⇒x-y=-4
⇒0-y=-4
⇒-y=-4
⇒y=4
∴ x=0, y=4
Answer:
53.47
Step-by-step explanation:
The Probability of choosing a green marble out of total 29 marbles is 11/29.
What is the Probability?
Probability defines the likelihood of occurrence of an event. There are many real-life situations in which we may have to predict the outcome of an event. We may be sure or not sure of the results of an event. In such cases, we say that there is a probability of this event to occur or not occur.
Total number of marbles = 11 Green + 18 Silver = 29 marbles
Number of Green marbles = 11
Probability = Number of green marble / Total number of marbles
= 11 / 29
Thus, The Probability of choosing a green marble out of total 29 marbles is 11/29.
