I would add like terms, meaning subtract 6.4 from both sides.
3.5n = 36.1
1/3 + 5/6 + 5/12
1.583333333333333
Answer:
c=4
Step-by-step explanation:
–2c = –c − 4
add c to both sides
-1c=-4
divide both sides by -1
c=4
In the smaller triangle, let 
be the length of the smallest leg. Then the smallest leg in the larger triangle is 
.
Within the scope of the smaller triangle, we have such that
Then within the larger the triangle, we would have
Now we can solve for 
:
Since 10 cm is bigger than 1 mm, the scale drawing is bigger
