Answer:
So the width is 3.25
Step-by-step
If the perimeter of a rectangle is 300 and the length is two times the
width, what are the length and the width?
*Please don't get upset if this is incorrect, I am in 9th grade and I have severe dyslexia and dyscalculia*
:)
Given the length is 3 more than the width, and the perimeter is 26 inches, by solving the equation corresponding to the perimeter of the rectangle, we find that the width of the rectangle is 5 inches.
The question is asking for the width of a rectangle given that its length is 3 more than its width and the perimeter is 26 inches. Let's denote the width as x. Therefore, the length is x + 3.
The formula for the perimeter of a rectangle is 2*(length + width), which in this case translates into 2*(x + (x + 3)). As given, this equals 26. Solving the equation 2*(2x + 3) = 26, we find that x = 5. Therefore, the width of the rectangle is 5 inches.

===================================================
Explanation:
To get the unit cost, we divide the total cost over the number of pounds.
We can do this for any row
You don't need to show all four row calculations. You can simply pick one row.
This tells us that each pound costs $1.75
Put another way: the price is $1.75 per pound
Annie and Brian traveled 18.3 hours and 1.7 hours respectively
Simultaneous Linear Equations can be solved using one of the following methods :
Let's try to solve the problem now.
Let :
Annie's number of hours = A
Brian's number of hours = B
If Annie traveled 5 times the sum of the number of hours brian traveled and 2 , then it could be written as :
→ Equation 1
If together they traveled 20 hours , then it could also be written as :
← Equation 1

Hi there! :)
C. has both jump and infinite discontinuity.
Evaluate both piecewise functions at x = 1;
1 / (x + 1) = 1 / ((1) + 1) = 1/2
2x - 1 = 2(1) - 1 = 1
As the piecewise functions contain different y-values when evaluated at
x = 1, there is a jump discontinuity at x = 1.
However, the first function also contains a vertical asymptote or infinite discontinuity where it is undefined, or at x = -1. (1 / 0 = undefined). This means that the function also contains an infinite discontinuity.
Therefore, the correct choice is:
C. has both jump and infinite discontinuity.
