Answer:
Speed of plane in still air = 825 km/h
Step-by-step explanation:
Given:
Speed of plane with the wind is 145 km/h faster than what it would have with still air.
Speed of plane with wind = 970 km/h
To find speed of plane in still air.
Solution:
Let speed of plane in still air be = 
km/h
Thus speed of plane with wind would be given as = 
km/h
Speed of plane with wind is given =970 km/h
So, we have:
Solving for .
Subtracting both sides by 145.
∴ 
km/h (Answer)
Thus, speed of plane in still air = 825 km/h
Answer:
135
Step-by-step explanation:
you subtract 160 from 25
you get 135
to check you do 135 + 25 and you get 160
Each step subtracts 3 from the previous number.
14 - 3 = 11
11 - 3 = 8
The sequence will continue:
8 - 3 = 5
5 - 3 = 2
2 - 3 = -1
Etc.
14, 11, 8, 5, 2, -1...
Answer:
"no more than 5"
"less than or equal to 5"
.
I can't see your inequalities or the thing your question called expressions.
Step-by-step explanation:
If is no more than it is less than or equal to.
So no more than 5 means less than or equal to 5.
