Its A because when you do (x-5)=0 you add 5 to get x=5 and thats your x value and the 3 for your k is your y value
Answer:
Step-by-step explanation:
<u>Given</u>
- DE = 3x + 2, EF = x + 5, DF = 23
<u>As per segment addition postulate</u>
<u>Substituting values:</u>
- 3x + 2 + x + 5 = 23
- 4x + 7 = 23
- 4x = 16
- x = 4
Answer:
The tank is 10cm high
Step-by-step explanation:
Given
-- length
-- width
--- water lever
Required
The height of the tank
Let y represents the remaining fraction before water is added.
So:
Make y the subject
Solve
Represent the volume of the tank with v
So:
Make v the subject
Substitute:
Represent the height of the tank with h;
So, the volume of the tank is:
Make h the subject
Substitute values for v, l and w
Convert 30L to cm^3
Step-by-step explanation:
Thus, option C is the correct answer.
