18+B=N
Explanation - The variable B is unknown, meaning that you are not able to place a number in its place.
There are many ways you can go about doing this. One example is 430÷2=215. I am assuming you are doing multiplication at this time, or you have a calculator nearby. A way you would solve this is choosing a number between 200 and 250, then multiply that by "x"(any number you so choose). The number you would get is "y"(the product of x×your number between 200 and 250). Your equation would then be y÷x=number you choose between 200-250
Answer:
x = -1
Step-by-step explanation:
l (length)=3x
P (perimeter)= 8x+6 = 2 x length + 2 x width
8x+6 = 2 (3x) + 2 x width
8x+6 = 6x + 2 x width
2 x width = 8x+6 - 6x
2 x width = 2x+6
width = 1/2(2x+6) = x + 3

(128)/(360) = (32)/(total people)
solve for (total people)...
(128)(total people) = (32)(360)
total people = (32)(360)/(128) = 90 people total
