The answer is the additive identity postulate.
Rom4ik [11]3 years ago

Answer:

The additive identity postulate

Step-by-step explanation:

6 + 0 = 6

Any number added with zero, we get the same number.

That is, a + 0 = a, where "a" is any real number.

Let's take a = 9, we get

9 + 0 = 9

Let's check out a few more examples:

-9 + 0 = -9

2/3 + 0 = 2/3

22 + 0 = 22

You can see any number added with 0, we get the same number.

Here 0 is additive identity, this is called additive identity postulate.

We are given 6 + 0 = 6 which illustrated by "The additive identity postulate."

Therefore, answer is "The additive identity postulate"

Rectangles ABCD and EFGH have the same shape. What is the length oh FG
tangare [24]
The length of FG would be BC. This is because FG and BC corresponds on the shape letter sequence. This would mean that EF would be AB, that GH would be CD, and that HE would be DA.

Your friend says that the absolute value equation ∣3x + 8 ∣ − 9 = −5 has no solution because the constant on the right side of t
SashulF [63]
No, ur friend is not correct

| 3x + 8 | - 9 = -5....u have to get the absolute value (and everything in it) on one side of the equal sign, and everything else on the other side. So we have to get that -9 across the equal sign by adding 9 to both sides
| 3x + 8 } = -5 + 9
| 3x + 8 | = 4...so that number is not negative anymore
now u can set up ur 2 equations and solve for x...ur 2 equations would be: 
3x + 8 = 4 and 3x + 8 = -4...so there will be 2 solutions

** if that -9 would not have been there, then ur friend would have been correct

Is the mistake one two three or is their no mistake
maria [59]

Answer:

the mistake is that to "remove" the 1/2 on the left you would have to multiply by 2 (or divide by 1/2 but no one does that)

the result would be that 2h-4 = 10  should actually be 2h-4 = 20

Please help :) :) :)
Hatshy [7]

<span>A motorboat travels 222 km in 6 hours going upstream.
Rate = distance/time = 222/6 = 37 km/hr
----------------------
It travels 390 km going downstream in the same amount of time.
Rate = distance/time = 390/6 = 65 km/hr
---------
What is the rate of the boat in still water and what is the rate of the current?
Equations:
Upstream: b-c = 37 km/hr
Downstrm: b+c = 65 km/hr</span>

<span>Add and solve for "b":
(2)b = 102 km/hr
b = 51 km/hr (speed of the boat in still water)
-----
Solve for "c":
b+c = 65
51 + c = 65
c = 14 km/hr (speed of the current)</span>
