Step-by-step explanation:
so let's assume they both sold for 100 each the first article sold for 10% laws there by cost of article is 111.11 rounded the second article made 25% profit so cost must be 80 total cost is 8.89 or 5% profit I'm so sorry if im wrong
Step-by-step explanation:
The GCF of 28 and 80 is 4.
<u>Distribute 4 for 28 and 80, then solve:</u>
![4(7) + 4(20) = 28 + 80](https://tex.z-dn.net/?f=4%287%29%20%2B%204%2820%29%20%3D%2028%20%2B%2080)
![4(7 + 20) = 28 + 80](https://tex.z-dn.net/?f=4%287%20%2B%2020%29%20%3D%2028%20%2B%2080)
![4(27) = 28 + 80](https://tex.z-dn.net/?f=4%2827%29%20%3D%2028%20%2B%2080)
![108 = 80 + 28](https://tex.z-dn.net/?f=108%20%3D%2080%20%2B%2028)
Answer:
5 ft
Step-by-step explanation:
If all sides are of the same length, we can multiply the value of one side by 3, because a triangle has three sides (and the perimeter is all sides added together), to find the perimeter.
× 3
can be rewritten as
, so:
× ![\frac{3}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B1%7D)
![= \frac{15}{3}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B15%7D%7B3%7D)
The numerator & denominator share a common factor of 3, so:
5 ft is the final answer/perimeter.
hope this helps!
Isolate the variable by dividing each side by factors that don't contain the variable.
l = v/wh
w
h
