Answer:
480/(x+60) ≤ 7
Step-by-step explanation:
We can use the relations ...
time = distance/speed
distance = speed×time
speed = distance/time
to write the required inequality any of several ways.
Since the problem is posed in terms of time (7 hours) and an increase in speed (x), we can write the time inequality as ...
480/(60+x) ≤ 7
Multiplying this by the denominator gives us a distance inequality:
7(60+x) ≥ 480 . . . . . . at his desired speed, Neil will go no less than 480 miles in 7 hours
Or, we can write an inequality for the increase in speed directly:
480/7 -60 ≤ x . . . . . . x is at least the difference between the speed of 480 miles in 7 hours and the speed of 60 miles per hour
___
Any of the above inequalities will give the desired value of x.
Answer:
Step-by-step explanation:
<h3>Given</h3>
<h3>To find</h3>
<h3>Solution</h3>
Area formula
- A = lw
- A= 5w*w= 5w²
- 5w² = 500
- w²= 100
- w = √100
- w = 10 m
Then
Answer:
-3, -4, -5, -6, -7, -8
Step-by-step explanation:
Im not sure if that is what you are looking for or if you want x ≤ -3 and x ≥ -8
The answer would be A. 15mi
Answer: ok the answer is 42
Step-by-step explanation: so q = 17 right? and 25 = Y
so i think you add then you get 42...right? i might not get the right answer
but what letter is this i don't know this symbol or lettter: π
