The speed of the jet is 1302 miles per hour.
<h3><u>Speed determination</u></h3>
Since a private jet can fly 1134.6 miles against a 27-mph headwind in the same amount of time it can fly 1469.4 miles with a 27-mph tailwind, to find the speed of the jet you must perform the following calculation:
- (1469.4 - 1134.6) / 2 = X
- 334.8 / 2 = X
- 167.4 = X
- 1469.4 - 167.4 = X
- 1302 = X
Therefore, the speed of the jet is 1302 miles per hour.

Answer: The initial number of shoes in the store is 300.
Step-by-step explanation:
Given : Kelly is a salesperson at a shoe store, where she must sell a pre-set number of pairs of shoes each month.
At the end of each work day the number of pairs of shoes that she has left to sell that month is given by the equation
, where S = Number of pair of shoes Kelly still needs to sell.
x = Number of days she has worked that month.
When x= 0 , we get S= 300
i.e. When she started working in that month , she has 300 pairs of shoes to sell.
Therefore , Number 300 means that the initial number of shoes in the store is 300
I don't like that is not a question
The answer is x is greater than 4.
We simplify the answer by adding and subtracting like terms to isolate x, so I want to get rid of the 8 on the side of x so let's subtract it from that side, and what we do on one side we must do to the other side.
12 -8= 4
x+8 -8= x
So now we have 4 on the left side and x on the right side, plug the inequality back and we have our answer!
