A group of 8 friends went to lunch and spent a total of $76, which included the food bill and a tip of $16. They decided to
split the bill and tip evenly among themselves
Which equations and solutions describe the situation? Select two options,
The equation (x+18) -
represents the situation, where x is the food bil,
The equation
(% 15) - 18 represents the situation, where x is the food bill
The solution
80 represents the total food bill
The solution
80 represents each friend's share of the food till and tip
The equation B12 15- 78 represents the situation, where
is the food bl.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

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'.
