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
Answer:
(5(x-1))/3x
Step-by-step explanation:
8(10-K) = 2k
mutiply the bracket by 8
(8)(10)= 80
(8)(-k)= -8k
80-8k= 2k
move -8k to the other side
sign changes from -8k to +8k
80-8k+8k= 2k+8k
80= 2k+8k
80= 10k
divide by 10 for both sides
80/10= 10k/10
k= 8
Answer: k= 8
You cant subtract from a multiplication expression.
If there is a way.. im not sure.
