The first number will be 500
the second number will be 600
and the last number will be 990
Answer:
-x + 10
Step-by-step explanation:
(x + 7) - (2x-3)
x + 7 - 2x - 3
x - 2x
-x + 7 + 3
-x + 10
The experimental probability of the computer generating a 2 is 20%.
<h3>What is the experimental probability?</h3>
The experimental probability determines the odds an event would happen based on the results of an experiment.
Experimental probability = ( number of times a 2 was generated / total number of numbers generated) x 100
(16 / 80) x 100 = 20%

The simultaneous equations are
2x - 7y = 4 (1)
3x + y = -17 (2)
Write (2) as
y = - 3x - 17 (3)
Substitute (3) into (1).
2x - 7(-3x - 17) = 4
2x + 21x + 119 = 4
23x = -115
x = -5
This is the equation obtained after substituting y from the second equation into the first equation.
The solution for y is
y = -3(-5) - 17 = -2
Answer: x = -5
Note: The solution is x = -5, y = -2.
