Answer:
In decimal form, the value of pi is approximately 3.14. But pi is an irrational number, meaning that its decimal form neither ends (like 1/4 = 0.25) nor becomes repetitive (like 1/6 = 0.166666...). (To only 18 decimal places, pi is 3.141592653589793238.)May 17, 1999
Step-by-step explanation:
1. y=7-3x
4x+2(7-3x)=16
4x+14-6x=16
-2x=2
x=-1
-3+y=7
y=10
(-1,10)
2. x=2y
2(2y)+2y=4
4y+2y=4
6y=4
y=2/3
x-2(2/3)=0
x-4/3=0
x=4/3
(4/3,2/3)
Answer:
The answer simplifies to zero
Step-by-step explanation:
3 sqrt(128) - 2 sqrt(6) * 4 sqrt(3)
3 sqrt(128) - 8 sqrt(6*3)
3sqrt(128) - 8 sqrt(18)
3 sqrt(64*2) - 8 sqrt(9*2)
3 sqrt(64)sqrt(2) - 8 sqrt(9) sqrt(2)
3 * 8 * sqrt(2) - 8 * 3 * sqrt(2)
24 sqrt(2) - 24 sqrt(2)

Answer: addition property of inequality</h3>
================================================
Explanation:
These are the steps to focus on
step 3: -6x - 8 < -2
step 4: -6x < 6
The move from the third step to the fourth step has us adding 8 to both sides. Therefore, we use the addition property of inequality.
That property has four forms
- If
then 
- If
then 
- If
then 
- If
then 
It's similar to the idea of starting with a = b, then adding c to both sides to get a+c = b+c
We add the same thing to both sides to keep things balanced.
5 to the power of 2 = 25
9 to the power of 2 = 81
25 + 81 = 106
Square root of 106 = 10.29563
If you round it to the nearest hundredth, it will become 10.30
If you round it to the nearest tenth, it will become 10.3
