Answer/Step-by-step explanation:
Given:
86.32947
Let's find the place value of each digit
8 => tens which is 80
6 => unit which is 6
3 => tenth which is 0.3
2 => hundredth which is 0.02
9 => thousandth which is 0.009
4 => ten-thousandths which is 0.0004
7 => hundred-thousandth which is 0.00007
If you add all of the it will give you 86.32947
Thus:
1. 6 => b
2. 8 => g
3. 4 => e
4. 7 => d (there's a mistake in the number of zeros written.)
5. 9 => c
I will have to assume that you actually meant " e^(ln 7x). The exponential and logarithmic functions are inverses of each other, so d^(ln 7x) = 7x (answer C).
Think about you have a pizza. you have 6 people and a total of 12 slices. How many can each person get? 2.
This is the same thing. $2.47 divided by 6 people = $0.46 cents each
The error is in the second step they subtracted 3 from both sides but it was a 3x, which you can not do.
Correction.
9x+18+3x=1
12x+18=1
12x=-17
x=-17/12
