Answer:
y = (2/7)x -12 (Answer Choice B)
Step-by-step explanation:
Take the given values ( m=2/7 and y-intercept (0,-12) ) and substitute them into y = mx + b:
y = (2/7)x -12
75% of n is 375.
Step-by-step explanation:
Given,
45% of a number n = 225
We will find n first.
![\frac{45}{100}n=225\\0.45n=225](https://tex.z-dn.net/?f=%5Cfrac%7B45%7D%7B100%7Dn%3D225%5C%5C0.45n%3D225)
Dividing both sides by 0.45
![\frac{0.45n}{0.45}=\frac{225}{0.45}\\n=500](https://tex.z-dn.net/?f=%5Cfrac%7B0.45n%7D%7B0.45%7D%3D%5Cfrac%7B225%7D%7B0.45%7D%5C%5Cn%3D500)
Now we have to find 75% of n.
75% of n = ![\frac{75}{100}*500=75*5](https://tex.z-dn.net/?f=%5Cfrac%7B75%7D%7B100%7D%2A500%3D75%2A5)
75% of n = 375
75% of n is 375.

If the perimeter is 30
and the length is twice the width
c=length
w=width
2c=w
a pool table has 4 sides, the two adjacent sides will be equal so we only need to account for 1 of the widths and 1 of the lengths
meaning we only need to use half of the perimeter, or 15
if the length is twice as long as the width
the length would be 10
the width would be 5
there are two widths and 2 heights so the perimeter would correctly add up to 30 feet, proving you have the right answer
Answer:
0
Step-by-step explanation:
If the event is not possible it's not going to happen
1 km = 0.621371 miles
5 km = 5 x 0.621371 = 3.106855 miles
1 mile = 5,280 feet
3.106855 miles x 5,280 = 16,404.1944 feet
1 foot = 12 inches
16,404.1944 feet x 12 = 196,850.3328 inches
