80%x + x = 216
0.8x + x = 216
1.8x = 216
x = 216/1.8
x = 120
hope this help
The distance is about 5.8 units.
Well it has to be either 23 or 9 because you have to add the two smallest sides also you have to subtract them . What are the options ?
Do you mean Divide the answer by 4?
Anyway you need to make the "n" by itself so add 8 to both sides.
Answer:
undefined/no solution
Step-by-step explanation:
you use elimination to solve. So multiply 2x+4y=-12 by 1 and x+2y=-2 by 2. then you subtract 2x+4y=-12 by 2x+4y=-4 and get 0y=-8. Anything divided by 0 is undefined/no solution because you can't divide anything by 0.
