Step-by-step explanation:
1.6a= -9.12
a= -9.12/1.6
=−5.7
option B
Answer:
x = 35
Step-by-step explanation:
1. Add all angles
![115+(x+36)+24+(2x+10)+2x](https://tex.z-dn.net/?f=115%2B%28x%2B36%29%2B24%2B%282x%2B10%29%2B2x)
= ![5x+185](https://tex.z-dn.net/?f=5x%2B185)
2. Match 360 and fix
![5x+185=360](https://tex.z-dn.net/?f=5x%2B185%3D360)
![5x=360-185](https://tex.z-dn.net/?f=5x%3D360-185)
![5x=175](https://tex.z-dn.net/?f=5x%3D175)
![x=175/5](https://tex.z-dn.net/?f=x%3D175%2F5)
![x=35](https://tex.z-dn.net/?f=x%3D35)
Hope this helps
So using standard form you convert the equation to 5x - 2y = -10 then use slope m of a line of the form Ax + By = C equals negative a over b. It would be a = 5 b = -2 m = -5/-2 m = 5/2. Have a good day the answer is 5/2
Answer: The number of letters that must be engraved for the costs to be the same is 125.
Step-by-step explanation:
Since we have given that
![0.4e+10+15=0.20e+5+25](https://tex.z-dn.net/?f=0.4e%2B10%2B15%3D0.20e%2B5%2B25)
We need to find the number of letters.
![0.4e+25=0.2e+30\\\\0.4e-0.2e=30-25\\\\0.2e=25\\\\e=\dfrac{25}{0.2}\\\\e=125](https://tex.z-dn.net/?f=0.4e%2B25%3D0.2e%2B30%5C%5C%5C%5C0.4e-0.2e%3D30-25%5C%5C%5C%5C0.2e%3D25%5C%5C%5C%5Ce%3D%5Cdfrac%7B25%7D%7B0.2%7D%5C%5C%5C%5Ce%3D125)
Hence, the number of letters that must be engraved for the costs to be the same is 125.
