Answer:Let x be the number of kilograms he sold in the morning.Then in the afternoon he sold 2x kilograms, so the total is x+2x=3x This must be equal to 360.Therefore, the salesman sold 120 kg in the morning and 240 kg in the afternoon.
Hope this helps :)
Answer:
m∠K = 36°
m∠L = 54°
m∠M = 90°
Step-by-step explanation:
A triangle's angles add up to 180 degrees. We will add together all the angles and set them equal to 180. Then, we will solve for x. Lastly, we will solve for the angle measurements.
-> The little "box" in angle M means that it is equal to 90°
90° + (2x + 42)° + (4x + 12)° = 180°
90° + 42° + 12° + 2x° + 4x°= 180°
144° + 6x°= 180°
6x° = 36°
x = 6°
[m∠K]
4x + 12
4(6) + 12
36°
[m∠L]
2x + 42
2(6) + 42
54°
Multiply 20 by 5 and you get 100, please tell if this is what you wanted!
Answer:
-10
Step-by-step explanation:
Write out the equation
5n-8=n-48
move like terms to the same side
4n=-40
divide 4n and 4 by 4 to get n by itself.
n=-10
