Write the correct equation. Direct variation problems are solved using the equation y = kx. When dealing with word problems, you should consider using variables other than x and y, you should use variables that are relevant to the problem being solved. Also read the problem carefully to determine if there are any other changes in the direct variation equation, such as squares, cubes, or square roots.
13/2 = 6.5
2/13 = 015
6.5-0.15 = 6.35
Step-by-step explanation:
Answer:
it has 11 faces 10 sides for the decagon + 1 for the base
It does have one face that is a decagon, which is the base, the rest are triangles
it has 20 edges
Step-by-step explanation:
X/15=4/16 def of similar triangle by AAA
x = 60/16=5/2
