Five less than three times the length l

The expression could be written as: 3L-5.

Step-by-step explanation:

We are asked to find an variable equation/ expresssion for the following world problem:

      " Five less than three times the length L".

for this we have to firstly take '3' times the length  'L' (i.e. 3L) and then subtract that expression by 5 to make it five less than three times the length 'L' and hence obtain our required expression.

Hence, the expression is represented as:  3L-5

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
