Answer:
The cost of 8 comic books is $14
Step-by-step explanation:
Given
Required
Determine the cost of 8 books
First, we need to determine the cost of 1 book
Divide through by 20
Then multiply both sides by 8 to get the cost of 8
Hence;
<em>The cost of 8 comic books is $14</em>
y = 3
The opposite sides of a rectangle are equal thus
2y + 4 = 10
subtract 4 from both sides
2y = 10 - 4 = 6
divide both sides by 2
y = 
= 3
If there are multiple operations at the same level on the order of operations off from left to right and you work like this first noticed that there are no parentheses or exponents so we moved to multiplication and division with any sense of parentheses
Remember that
is
. We know form our problem that
and
, so:
Now, to find
, we just need to evaluate
at 3. In other words, we are going to replace
with 3:
We can conclude that the correct answer is <span>
C.6(3) – 4 + 3^2 </span>
