Answer:
n=80
Step-by-step explanation:
n/4=20
(n/4=20)4 . to get rid of the denominator u multiply by 4 on both sides
n=80
Answer:
B
Step-by-step explanation:
The diagram shows four points through which the line of proportional relationship should pass. One of these points has coordinates (8,28).
The line representing proportional relationship is always straight line passing through the origin and has the equation
![y=kx,](https://tex.z-dn.net/?f=y%3Dkx%2C)
where k is the coefficient of proportionality.
Substitute coordinates of known point into the equation:
![28=k\cdot 8\\ \\k=\dfrac{28}{8}=\dfrac{7}{2}=3.5,](https://tex.z-dn.net/?f=28%3Dk%5Ccdot%208%5C%5C%20%5C%5Ck%3D%5Cdfrac%7B28%7D%7B8%7D%3D%5Cdfrac%7B7%7D%7B2%7D%3D3.5%2C)
so the coefficient of proportionality is equal to ![3.5.](https://tex.z-dn.net/?f=3.5.)
Answer:
The answer is: y = - |x+1|+1
The dimensions in the given should have the same unit in order for us to do mathematical operations with them. 3.5 km when converted to meters become 3500 m. The problem asked for the tiger's displacement, that is the distance from his starting point to his final position. This is equal to 1,250 m subtracted from 3500 m. Thus, the answer is 2250 meters.
