<em><u>Answer:</u></em>
True
<em><u>Step-by-step explanation:</u></em>
So, again, from the most right column, we can add 5, -6, and -2 to get -3. We now know that every row or column must be equal to -3.
The question is asking if the number square below is -3. We found out from above that is -3 so it's true.
Answer:
13
Step-by-step explanation:
Answer:
A) 5x - 2y = 12
B) 3x + 2y = 36 Adding both equations eliminates "y"
8x = 48
x = 6 Putting x=6 into equation B we get
3*6 + 2y = 36
2y = 18
y = 9

Answer:
The object travels 144,000,000 feet.
Step-by-step explanation:
The distance the object travel after t seconds is given by:
How far would the object travel after 1.5 * 10^3 seconds
This is d when 
, so 
The object travels 144,000,000 feet.
The circumference of a circle is equal to the diameter times pi. So, let's look at what happens if you double the radius of a circle -- say from 2 to 4. The area will go from 12.56 to 50.24. This means that it has quadrupled.
