50% of 10 is just half so half of 10 is 5
The answer is five
Let's call that number x, twice the number will be 2x, sum of it and 5 is, 2x+5. So if this expression is at most 15, it means, it can be only less than 15 and equal to 15. Let's show this as an inequality.

Let's solve.

![x\quad \in \quad \left[ -\infty ,5 \right]](https://tex.z-dn.net/?f=x%5Cquad%20%5Cin%20%5Cquad%20%5Cleft%5B%20-%5Cinfty%20%2C5%20%5Cright%5D%20)
If the number is a natural number. The values it can take is,
<span>3 - (2 - 8)
= 3 - 2 + 8
= 11 - 2
= 9
In short, Your Answer would be Option B
Hope this helps!</span>
Answer:
TRUE sorry
Step-by-step explanation:
Answer:
(P-2l)/2 =w
Step-by-step explanation:
P = 2l + 2w
Subtract 2l from each side
P -2l = 2l-2l + 2w
P-2l = 2w
Divide by 2
(P-2l) /2 = 2w/2
(P-2l)/2 =w
