Answer: The numerical length of
is 20 units.
Step-by-step explanation:
Given: Point T is on line segment
.
i.e.
(i)
Since , it is given that ST=2x+6,TU=4, and SU=4x
Substitute these values in (i), we get

Now, the numerical length of 
Hence, the numerical length of
is 20 units.
The answer is 8. Hope it helps :)
So here is the answer. Given that both Eric and Mark got a hamburger which is $4 each. Mark got a lemonade and some cotton candy which costs $5.
So this gives them a total of $4, $4, $5, $?(lemonade). Partial sum is $13 without the lemonade. Since Eric got a $2, the total bill was deducted with $2 and the rest of the amount is $14.50. Therefore, the total bill would have been $16.50. So $16.50 minus $13 (partial sum) is $3.50. So the lemonade costs $3.50. Hope this helps.
