the equation for the stated problem would be:
3x ≥ -6
It would show the average time spent on the homework.
And the average distance between the mean and the lowest and highest numbers in the data.
Answer:
9
Step-by-step explanation:
2x=28-10
2x=18
x=18÷2
x=9
This is hard to write... I hope this makes sense to you...
3x-2y=-39
x+3y= 31
We want to use elimination therefor, we need to either get our x or our y to add together to get zero.
To do this, we will multiply -3 to (x=3y=31)
NEW EQUATION
3x-2y=-39 PLUS
-3x-9y= -93 Equals
Answer: -11y= -54
y= 4.9
Plug in to solve for x (put new y in)
3x-2(4.9)=-39
x= -9.73
