um you need to be more specific on the question bud
Answer:
Over a 22 seconds, the altitude will be: 924 feet
Step-by-step explanation:
- Let 'x' be the time in seconds
As the altitude of an airplane is decreasing at a rate of 42 ft per second.
Thus, the expression to find the altitude at x seconds is:
y = 42x
so at x = 1 sec, y = 42 feet
Now, putting x = 22 seconds to determine the altitude at 22 seconds
y = 42x
= 42(22)
= 924 feet
Thus, over a 22 seconds, the altitude will be: 924 feet
Nice you do not know the price of the child's ticket, you represent it as X. Then you add the 2.75 to the variable. You take the unknown number and add the known. so the answer would be x+2.75
If your solving for t then t = 4.5
