Matter exists in three states; <em>solid, liquid and gas.</em>
The statement that corrects the error in his table is:
<em>D. The Solids column and the gas column should be switched because solids have a definite shape and volume and gases have no definite shape or volume.
</em>
<em />
<em />
Looking at the table, we have the following observations.
- <em>The solid column shows indefinite shape (because the particles fill in the container)</em>
- <em>The liquid column is properly cataloged</em>
- <em>The gas column shows a definite shape</em>
<em />
Solid has definite shape, while gas doesn't.
To make corrections, Marcus needs to switch the gas and the solid column.

Answer:
B) y < 3/4x -2
Step-by-step explanation:
First, to eliminate 2 options let's see what sign we should use. The ≤ is a solid line where < is a dotted line. Next, you need to know which way to flip the sign. If it is under the line it is the < symbol.
answer x = 225 and y = -135
Step-by-step explanation:
x+y = 90 and x= 90-y and x -y = 360 so 90-y -y = 360
Answer:
5 < 8
-4 < 0
0 < 4
-5 < 5
-9 > -19
-5 > -8
Step-by-step explanation:
Remember, the "Alligator" or better known as the "Packman" symbol ( > < )
It will always want to "eat" the bigger number. so, 8 is bigger than five, so the "Packman" will want to go after the bigger number. 5 < 8
The speed of wind and speed of plane in still air are 23 and 135
km/h respectively.
<u>Step-by-step explanation:</u>
Let the speed of wind and speed of plane in still air are w and p km/h respectively.
The effective speed on onward journey was
................(1)
The effective speed on return journey was
..............(2)
Adding equation (1) and equation (2) we get,
⇒ 
⇒ 
⇒ 
Putting value of in we get:
⇒
⇒ 
⇒ 
Therefore ,The speed of wind and speed of plane in still air are 23 and 135
km/h respectively.
