Answer:
A
Step-by-step explanation:
Probably d as the the temperature outside is unpredictable and the we know the time is always going up
1/3x + y = 4....subtract 1/3x from both sides
y = -1/3x + 4 <===
Answer:
20 gray squares
Step-by-step explanation:
Given
See attachment for squares
Required
Number of gray squares when white = 16
First, we calculate the equation that represents both squares.
<u>The white squares</u>
--- initial
-- difference between successive gray squares
So, the nth term is:
<u>The gray squares</u>
--- initial
-- difference between successive gray squares
So, the nth term is:
When the white squares is 16
--- Calculate n
To get the number of gray squares;
Substitute in
