Answer:
120(I'm not definitely sure)
Step-by-step explanation:
IQR= Q3- Q1= 170 - 50 = 120
The number of different codes does this lock provides is 360.
Given that,
- There is the combination lock having push buttons from A to F (6 buttons)
- Out of this, four should be in any order.
- Also, the push button should not be used more than once.
Based on the above information, here we use permutation which is as follows:

= 360
Therefore we can conclude that the number of different codes does this lock provides is 360.

Answer:
the answer is 0
Step-by-step explanation:
Add -4x and 3x to get -x. then divide -1 on both sides. x=-2
Answer:
no solution
Step-by-step explanation:
x+3y =9
Solve for y
Subtract x from each side
3y = -x +9
Divide by 3
3y/3 = - 1/3x +9/3
y = -1/3x +3
The y intercept is 3 and the slope is -1/3
3x+9y = 45
Subtract 3x from each side
9y = -3x +45
Divide each side by 9
y = -3/9 x +45/9
y = -1/3x +5
The y intercept is 5 and the slope is -1/3
There is no solution
The lines are parallel (same slope) but the y intercepts are different
