Answer:
11
Step-by-step explanation:
55/5 = 11
I would use the pythagorean theorem to find the lengths of each side. a² + b² = c².
Side AB is one we're looking for. If you make other right triangle with that same side you can see that one length is 4 and the other is 3. So, 4² + 3² = c² → 25 = c² → 5 = c. Side AB is length 5.
Side AC is another. Do the same with that side and you get that one length is 4 and the other is 3. (This is the same one as above) so side AC is length 5.
Side BC is the last one. One of the lengths is 1 and the other is 1 → 1² + 1² = c² → 2 = c² → 1.414213562 = c so side BC is approximately length 1.41.
Add each length up and you get a perimeter of roughly 11.4

Answer:
n = 95/14, or 6 11/14
Step-by-step explanation:
Let the number be n. Then:
n - 1 2/7 = 5 1/2.
Multiplying each term by the LCD (which is 14), we get:
14n - 18 = 77
Then 14n = 95
and so the desired result is n = 95/14, or 6 11/14
A way to solve this is finding 90% of 428.
428 × 0.90 = 385.2
Rounded, the answer is 385
