The width of rectangle is 21 meters.
Step-by-step explanation:
Given,
Perimeter of rectangle = 98 meters
Width of rectangle = w
Length of rectangle = w+7
Perimeter of rectangle = 2(Length+Width)
Perimeter = 

Dividing both sides by 4

Width of rectangle = 21 meters
The width of rectangle is 21 meters.

Answer:



And that's different from the claim of the student that:

The error of the student is that he/she changes the sign of the inequality from
to
and that's not possible since we don't multiply both sides of the equation by -1
Step-by-step explanation:
For this case we have the following inequality:

We want to rewrite the last expression with y in the left and x in the right so we can begin adding 3 in both sides of the inequality and we got:

Now we can divide both sides of the inequality by 2 and we got:

And that's different from the claim of the student that:

The error of the student is that he/she changes the sign of the inequality from
to
and that's not possible since we don't multiply both sides of the equation by -1

Answer:
(2,-2)
Step-by-step explanation:
The solution to a system of equations like these, is where the two lines intersect. In this case, I believe, it would be at point (2,-2). Although, it is a little hard to pinpoint without the labeled number lines.
Hope this helps! Best of luck!
