Answer:
It would be 36
Explanation:
<em>First:</em>
<em>Convert any mixed numbers to fractions.</em>
<em>Then your initial equation becomes:</em>
<em>108/1 ×1/3</em>
<em> </em>
<em>Applying the fractions formula for multiplication,</em>
<em>=108×1/1×3 = 108/3</em>
<em> </em>
<em>Simplifying 108/3, the answer is</em>
<em>=36</em>
hope it helped. :)
ALL yourr doing is just adding 8 and 36
y= 4\frac{1}{2} or y= 4.5
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:
3 terms
Step-by-step explanation:
4 4x and 9x
Call the price of the bike before mark up 'x', then we have:
x + 0.25x = 210
1.25x = 210
x = 168
Therefore, the bike cost $168 before 25% price increase.
