ANSWER:
Total fee per year = $6,600.
In which she have,
Now, we need to subtract it from total fee to get the remaining demand.
So, $6,600 - $3,500
Hence, Meghan will have to earn __$3,100__ to pay for the first year tuition.
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.
Answer:
see explanation
Step-by-step explanation:
product means to multiply, hence the product of 12 and k is
12 × k = 12k ( this is 84 means equal to 84 ), that is
12k = 84 ( divide both sides by 12 )
k = 7 ← is the solution
Answer:
You could use the equation y = mx + b to solve this problem. The m would equal 7.5 and the be would be zero, so the equation would be y = 7.5x + 0. Add values for x and you would get y.
