7*(15-a) = -56
Divide both sides by 7
15-a = -8
Subtract 15 from both sides
-a = -23
Divide both sides by -1
a = 23
Hope that's correct for you and it helps!!
Answer:
D. 9 inches
Step-by-step explanation:
By using proportionality theorem,
Triangle BLM ~ Triangle BAC
![\frac{bm}{bc} = \frac{bl}{ba}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bbm%7D%7Bbc%7D%20%20%3D%20%20%5Cfrac%7Bbl%7D%7Bba%7D%20)
as ba = bl + la and as bl = la
Therefore, bl + la = 2bl
![\frac{bm}{bc} = \frac{bl}{2bl}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bbm%7D%7Bbc%7D%20%20%3D%20%20%5Cfrac%7Bbl%7D%7B2bl%7D%20)
Now, we get,
![\frac{bm}{18} = \frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bbm%7D%7B18%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20)
as bc = 18
Hence,
![bm = 9 \: inches](https://tex.z-dn.net/?f=bm%20%3D%209%20%5C%3A%20inches)
The ten thousands place
