Answer:
The correct answer is: Option D) 5
Step-by-step explanation:
Given equation is:
In order to find that which values of x makes the equation true, we have to put each value of x in the equation. When both sides of equations will be equal, that value of x will be true for the equation.
Putting x = 2
Putting x = 3
Putting x=4
Putting x = 5
The equation is true for x = 5
Hence,
The correct answer is: Option D) 5
Answer:
b 125
Step-by-step explanation:
first you know that you have 2 and 5 as similar numbers you both square them so that they become a ratio of area which is 4/25 after you do 4/25=20/x and you do cross multiply then you find 125. hope that helped understand.
Answer:
t = 6.67 seconds
Step-by-step explanation:
Given that,
The distance of Moon from Earth, 
The speed of the spacecraft, 
We need to find the time it take this spacecraft to fly to the moon from earth. Let the time is t.
We know that,
Speed = distance/time
So, the required time is equal to 6.67 seconds.
