Use proportionalitie of sides so because this line with length 2x-8 is a midle segment line what mean that
2x-8 1
------- = --- => 2x -8 = 10 so 2x = 18 so x = 18/2 so x = 9
20 2
and so choice C. is right sure
The answer for this question is C.
First subtract the 3 from both sides to get : sqrt(x) = 10
Then square both sides to get: x = 100
The other equations can't simply proving that they cannot be radical equations
Hope this helps :)
Answer:
C, 3
Step-by-step explanation:
By creating a best line of fit you can get the sets of points (16,50) and (12,40)
Using these to find the slope we can get
-10/-4 is 2.5 The best approximation would be C, because if you round it up to the nearest number you would get 3.
We are given that the temperature is less than (<) -3 degrees Fahrenheit.
Since the temperature is represented by the variable "t", then t is less than -3.
So, the inequality which best describes the situation is:
t < -3
Checking the choices, we will find that the correct choice is:
<span>C: t < -3</span>
So let x be the cost for board
12,584 = 1704+x+x
12,584 = 1704+2x
12,584 - 1704 = 2x
10,880 = 2x
10,880/2 = x
5,440 = x
So the turion cost is 1704 + x
Which is 1,704+5,440 = 7144
