Answer:
x = 1
Step-by-step explanation:
2x + 1 = -1
2x = -1 - 1
2x = -2
x = -2 ÷ -2
x = 1
Answer:
![x=\frac{33}{7}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B33%7D%7B7%7D)
Step-by-step explanation:
Since ED is parallel to CA, the two triangles in the figure share all 3 angles and therefore must be similar. By definition, the corresponding sides of similar polygons are in a constant proportion.
Therefore, we have:
![\frac{11}{11+x}=\frac{14}{20},\\14(11+x)=20\cdot 11,\\11+x=\frac{20\cdot 11}{14},\\x=\frac{110}{7}-11=\boxed{\frac{33}{7}}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B11%2Bx%7D%3D%5Cfrac%7B14%7D%7B20%7D%2C%5C%5C14%2811%2Bx%29%3D20%5Ccdot%2011%2C%5C%5C11%2Bx%3D%5Cfrac%7B20%5Ccdot%2011%7D%7B14%7D%2C%5C%5Cx%3D%5Cfrac%7B110%7D%7B7%7D-11%3D%5Cboxed%7B%5Cfrac%7B33%7D%7B7%7D%7D)

Answer:
![\boxed {z = 6}](https://tex.z-dn.net/?f=%5Cboxed%20%7Bz%20%3D%206%7D)
Step-by-step explanation:
Solve for the value of
:
![\frac{1}{4} = \frac{1}{12} + \frac{1}{z}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20%3D%20%5Cfrac%7B1%7D%7B12%7D%20%2B%20%5Cfrac%7B1%7D%7Bz%7D)
-The variable
cannot equal to
since division by zero is undefined. SO, you multiply both sides by
, which is the least common multiple of
,
, and
:
![3z = 12z \times (\frac{1}{12}) + 12](https://tex.z-dn.net/?f=3z%20%3D%2012z%20%5Ctimes%20%28%5Cfrac%7B1%7D%7B12%7D%29%20%2B%2012)
![3z = z + 12](https://tex.z-dn.net/?f=3z%20%3D%20z%20%2B%2012)
-Take
and subtract it from
:
![3z - z = z - z + 12](https://tex.z-dn.net/?f=3z%20-%20z%20%3D%20z%20-%20z%20%2B%2012)
![2z = 12](https://tex.z-dn.net/?f=2z%20%3D%2012)
-Divide both sides by
:
![\frac{2z}{2} = \frac{12}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2z%7D%7B2%7D%20%3D%20%5Cfrac%7B12%7D%7B2%7D)
![\boxed {z = 6}](https://tex.z-dn.net/?f=%5Cboxed%20%7Bz%20%3D%206%7D)
So, the value of
of
.
