When Legs jumps 2 times and takes 13 steps forward, he lands in the same place as when he jumps 4 times and takes 5 steps backwa

tangare [24]

Answer:

9 steps

Step-by-step explanation:

Let $x$ be the number of jumps

and $y$ be the number of steps

So the first case

$2x+13y$

Second case

$4x-5y$

Both cover equal distances so

$2x+13y=4x-5y$

$\Rightarrow 2x-4x=-5y-13y$

$\Rightarrow 2x=18y$

$\Rightarrow x=9y$

So, one jumps is 9 steps.

The student council at King High School is planning a winter dance. The function rule, p=15t-700, shows the relationship between

maw [93]

(I) The 15 represents the money earned for each ticket sold
In other words the 15 is the cost of each ticket.

(II) The 700 represents the costs inquired when organizing the dance
In other words...how much it costs to throw the dance.

<u>Explanation</u>
Since t is the number of tickets and the function shows profit we know that every step on the left has some aspect to do with the profit....for ever ticket (t) sold there is an addition of 15 dollars...or for every 1 ticket sold $15 is earned....or each ticket costs 15 dollars

The -700 shows that 700 dollars must be subtracted from the total income from selling tickets....since this is looking for profit which is income-costs and we have already determined that 15t represents the income we know that the 700 must represent the costs of throwing the dance.
