Answer:
x = 12
Step-by-step explanation:
"Using the variable x for unknown number what is five more than the quotient of a number and 6 equals 7" translates into 5 + x/6 = 7.
To solve use inverse operations.
Sum/difference:
Let
This means that
Now, assume that is rational. The sum/difference of two rational numbers is still rational (so 5-x is rational), and the division by 3 doesn't change this. So, you have that the square root of 8 equals a rational number, which is false. The mistake must have been supposing that
was rational, which proves that the sum/difference of the two given terms was irrational
Multiplication/division:
The logic is actually the same: if we multiply the two terms we get
if again we assume x to be rational, we have
But if x is rational, so is -x/15, and again we come to a contradiction: we have the square root of 8 on one side, which is irrational, and -x/15 on the other, which is rational. So, again, x must have been irrational. You can prove the same claim for the division in a totally similar fashion.
The greatest possible temperature is and least possible temperature is
<u>Solution:</u>
Given that according to weather forecaster the temperature will be about -5 degree celsius given or take 10 degree”
Need to determine greatest possible temperature and least possible temperature.
Give and take in given statement means a temperature can go up by 10 degrees and can go down by 10 degrees
So greatest possible temperature will be
Least possible temperature will be
Hence according to weather forecaster, greatest possible temperature = and least possible temperature =
