Answer: 52
Explanation:
You need to replace the x-values with 8 to solve this. So, the equation would look like this. f(8)= 7 x 8 - 5
7 times 8 is 56. 56 minus four is 52 which is your answer.
If you needed to graph this then it would look like this... (8, 52)
The 8 is in the input because it is the x-value (we replace x with 8) and 52 is output/range/y-value because it is the answer.
Formula= Base times height divided by 2
6 x 7= 42
42/ 2
answer= 21
I did the PEMDAS method (P= parentheses, E= exponents, M= multiplication, D = Division, A= addition, S = subtraction.)
First I did what’s inside the parentheses, (6x2) and got 12.
Then I divided 16 by 22 and received 0.72.
I added 0.72 with 12 and the result was 12.72.
Last step was to subtract 12.72 - 8 and that equals 4.72
Current worlds population is 7.6 billion (7,600,000,000), so Japan’s population is equal to 1.67 % of the world’s population.
