-12 + 12 = 0
Step-by-step explanation:
3(-4) + 6(2) (multiply)
-12 + 12 = 0
Given:
Number of blue marbles = 6
Number of red marbles = 4
Number of green marbles = 4
Choose one marble without looking,
To find:
The probability that the selected marble is red or green.
Solution:
For the given problem,
Total outcomes = Total number of marbles
=
=
Favorable outcomes = Number of red or green marbles.
=
=
The probability that the selected marble is red or green, is
Therefore, the probability that the selected marble is red or green, is .

Answer: equations 1,3,4 and 5 stated has solutions.
Step-by-step explanation:
From the question, (x + 5) + 5 = (x + 5) + 5
The equations that represent the situation are:
1. x + 5 = (5 − x) − 5 :which has one solution
2. x + 5 = (x + 5) − 5 : many solutions
3. x + 5 = (x + 5) − 5: no solution
4. x + 5 = (5 − x) − 5 : many solutions
5. (x + 5) + 5 = (x + 5) + 5: many solutions
Equation 2 has no solution. While the other equations have one and more than one solutions.
