You just divide 15 by 3 and that equals 5
A rhombus is a 4 sided shape with equal lengths. Even though it has equal lengths, it has opposite sides that are parallel, and angles that are equal. It also has diaginols (dashed lines) meat in the middle
What you do is you rearrange and simplify both equations to have them in terms of y, and then graph them. If it asked for a solution, their point of intersection would be the solution.
The inequality would be the negative factor, because -5n+2n is 3n. You would write it on a number line like this.....
Sry, i was just making an educated guess.... RIP....
Do you have a picture or anything that you could show us?
