7:
3/8 = 6/x
3x = 48
x = 16
8:
4/5 = (x+7)/40
160 = 5x + 35
5x = 125
x = 25
9:
3/8 = 12/(x-3)
3x - 9 = 96
3x = 105
x = 35
10:
4/1 = (3x+6)/x
4x = 3x + 6
x = 6
Hole? It depends how big it is. Since there is no hole being depicted in this question, the answer is inexcusably 2ft
ANSWER
EXPLANATION
The given line JKL is a straight line. The angle on a straight line is 180 degrees.
This implies that the sum of the angles ![\begin{gathered} Solve for x in the equation above:[tex]\begin{gathered} x=180-30 \\ x=150\degree \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20Solve%20for%20x%20in%20the%20equation%20above%3A%3C%2Fp%3E%5Btex%5D%5Cbegin%7Bgathered%7D%20x%3D180-30%20%5C%5C%20x%3D150%5Cdegree%20%5Cend%7Bgathered%7D)
That is the value of x.
MISSING DETAILS
Yoko's fish tank has 17 liters of water in it. She plans to add 5 liters per minute until the tank has at least 57 liters. What are the possible numbers of minutes Yoko could add water?
Answer:
Minutes = 8 minutes
Step-by-step explanation:
Topic: Inequality
Given:
Available Size of water = 17 liters
Increment = 5 liters/minute
Size of water needed = At least 57 liters
Putting the above together, as have
17 + 5m > 57
where m represents total minutes and > represent at least
Solving the Inequality
5m > 57 - 17
5m > 40 ------ Divide through by 5
5m/5 > 40/5
m > 8
So, Yoko will need to add water for at least 8 minutes before she fills her tank to 57 liters.
