Answer:
67.17
Step-by-step explanation:
First, identify the hundreds digit (the 7)
Next, identify the next smallest place value (the 1)
Then, determine if 7 greater than or equal to 1. Yes, it is greater than 1, so round up. Increase the hundreds digit by one, so 7 becomes 8.
Finally, keep .17 and you get an answer of 67.17.
Let the number be x.
6*x - 8 = 34
6x - 8 = 34
6x = 34 + 8
6x = 42
x = 42/6
x = 7.
Let the number be y.
y/2
y/2 + 16 = 20
y/2 = 20 - 16
y/2 = 4
y = 2*4
y = 8.
The answer is B.
There are about 391,000 of plants currently known to science.
