Evaluate the expression shown for x=12 -5/6×+7
-5/6(12)+7
-10+7=-3
-3
To find the percentage of change, find the difference between the two by subtracting 31 from 62, leaving you with 31. Divide 31 by 62, which should give you 0.5. Multiply this number by 100, leaving you with 50%. There is a 50% change from 62 trees to 31 trees.
Answer:
Step-by-step explanation:
The average speed in function of the temperature:
The distance in function of the average speed:
x and S are the same
![D(t)=0.5*[6 \frac{miles}{hour} +0.1*\frac{miles}{hour*F}(80F-t)]](https://tex.z-dn.net/?f=D%28t%29%3D0.5%2A%5B6%20%5Cfrac%7Bmiles%7D%7Bhour%7D%20%2B0.1%2A%5Cfrac%7Bmiles%7D%7Bhour%2AF%7D%2880F-t%29%5D)
Answer:
The correct answer is: the rate of change is 1 cm per 2 weeks, or 1/2.
Step-by-step explanation:
I found a graph with the same problem, so I guess this is the graph to be based on. To find the rate, just determine the slope between any two points along the line. Suppose these points are: (30,10) and (50,20).
Slope = (20 - 10)/(50 - 30) = 1/2
The correct answer should be: the rate of change is 1 cm per 2 weeks, or 1/2.
2.36=2 36/100 turn into a fraction
2 36/100= 2 9/25 simplify (I divided by 4)
check if you can simplify again, if you can then do it, if you cant then thats your answer
So, the answer is 2 9/25
