Sam mark and jack were partners in business. sam and mark each receive twice as much of profit as jack did. if the total profit was 1800 how much did jack receive

360

Step-by-step explanation:

Let the profit of Jack be x , since Sam and Mark received twice as much of profit of Jack, then,

Sam's profit = 2x

Mark's profit = 2x

since the toatl profit = 1800 , then

x + 2x + 2x = 1800

5x = 1800

x = 1800/5

x= 360

Therefore Jack received 360

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
