Answer:
72 cupcakes
Step-by-step explanation:
Morgan can make 4 cupcakes with one cup of flour. She has 18 cups of flour and suppose she can make x cupcakes, then
1 cup of flour - 4 cupcakes
18 cups of flour - x cupcakes
Write a proportion:
![\dfrac{1}{18}=\dfrac{4}{x}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B18%7D%3D%5Cdfrac%7B4%7D%7Bx%7D)
Cross multiply:
![1\cdot x=18\cdot 4\\ \\x=72\ cupcakes](https://tex.z-dn.net/?f=1%5Ccdot%20x%3D18%5Ccdot%204%5C%5C%20%5C%5Cx%3D72%5C%20cupcakes)
Answer:
z = 17.5
Step-by-step explanation:
segment RX is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
=
, substitute values
=
( cross- multiply )
6z = 105 ( divide both sides by 6 )
z = 17.5
