Answer: e = 10
Step-by-step explanation: 9e + 4 = -5e + 14 + 13 e
Now lets bring the variables and numbers on a different side
Remember that when the numbers go to the other side the sign changes
so 4 - 14 = -9e + 13e -5e
-10 = -e
10 = e
if plug in both equations on a graph then you will see that when e = 10 the lines meet at 94.
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
