Answer:
1.90
Step-by-step explanation:
You would want to use a calculator since you need decimal places.
Once you type it into the calculator you should get 1.8952380952.
Since you're trying to simplify to the second decimal place, look at the third number after the decimal.
The 5 rounds up the 9 to a ten, which is represented by the 0.
That then turns the 8 into a nine.
Answer:
The linear equation can be written as
Step-by-step explanation:
Given that "Mr. Malone can heat his house in the winter by burning three cords of wood, by sing natural gas, or by combination of the two"
And his heating budget for the winter is $600
To find a linear equation that describes the problem:
Let the cords of wood be x and let sing natural gas be y
So that the combination of the cords of wood and sing natural gas is x+y
Now the linear equation can be written as

Answer
C. (5/2, -1/3)
Step by step explanation
Here we use the rational root theorem.
The possible roots are
+1, +3, +5, +15, +1/2, +3/2, +5/2, +15/2, +1/3, +5/3, +1/6 and +5/6
We have to use the synthetic division to find the correct root of this function.
Here the roots are 5/2 and -1/3
Others are not roots of this function.
Let's check x = 5/2 with synthetic division.
5/2) 6 -13 13 -39 -15
- 15 5 45 15
--------------------------
6 2 18 6 0
Similarly x = -1/3 is also root of this function.
Answer: C. (5/2, -1/3)
