The best answer is 1.435 ·103 because while they both are really small for a rail road track that one is bigger. the final answer for that is 147.805mm.
Answer:
Step-by-step explanation:
<u>This a form of the proportional relationship:</u>
- f(x) = kx, where f(x) - total cost, k- cost of each item, x - number of items
<u>We have:</u>
<u>It means:</u>
- Total cost of 5 cupcakes is $12
X-the $5 bills
y-the $10 bills
x+y=20
5x+10y=120
It's a system.
Draw (or do whatever) 13 in tens and ones [1 ten block ,3 ones blocks] then draw 7 in ones. then show the breaking apart of the tens block then subtract it by 7.
Answer:
![x + 5y - 2z + 14 = 0](https://tex.z-dn.net/?f=x%20%2B%205y%20-%202z%20%2B%2014%20%3D%200)
Step-by-step explanation:
A plane that passes through the point
with a normal vector of
has the following equation, initially:
![a(x - x_{0}) + b(y - y_{0}) + c(z - z_{0}) = 0](https://tex.z-dn.net/?f=a%28x%20-%20x_%7B0%7D%29%20%2B%20b%28y%20-%20y_%7B0%7D%29%20%2B%20c%28z%20-%20z_%7B0%7D%29%20%3D%200)
After we solve this, we have
![ax + by + cz + d = 0](https://tex.z-dn.net/?f=ax%20%2B%20by%20%2B%20cz%20%2B%20d%20%3D%200)
In this problem, we have that:
![(x_{0}, y_{0}, z_{0}) = (-5,-1,2)](https://tex.z-dn.net/?f=%28x_%7B0%7D%2C%20y_%7B0%7D%2C%20z_%7B0%7D%29%20%3D%20%28-5%2C-1%2C2%29)
![(a,b,c) = (−1,−5,2)](https://tex.z-dn.net/?f=%28a%2Cb%2Cc%29%20%3D%20%28%E2%88%921%2C%E2%88%925%2C2%29)
So
![a(x - x_{0}) + b(y - y_{0}) + c(z - z_{0}) = 0](https://tex.z-dn.net/?f=a%28x%20-%20x_%7B0%7D%29%20%2B%20b%28y%20-%20y_%7B0%7D%29%20%2B%20c%28z%20-%20z_%7B0%7D%29%20%3D%200)
![-1(x - (-5)) - 5(y - (-1)) + 2(z - 2) = 0](https://tex.z-dn.net/?f=-1%28x%20-%20%28-5%29%29%20-%205%28y%20-%20%28-1%29%29%20%2B%202%28z%20-%202%29%20%3D%200)
![-(x + 5) - 5(y + 1) + 2(z - 2) = 0](https://tex.z-dn.net/?f=-%28x%20%2B%205%29%20-%205%28y%20%2B%201%29%20%2B%202%28z%20-%202%29%20%3D%200)
![-x - 5 - 5y - 5 + 2z - 4 = 0](https://tex.z-dn.net/?f=-x%20-%205%20-%205y%20-%205%20%2B%202z%20-%204%20%3D%200)
![-x - 5y + 2z - 14 = 0](https://tex.z-dn.net/?f=-x%20-%205y%20%2B%202z%20-%2014%20%3D%200)
Multplying everything by -1
![x + 5y - 2z + 14 = 0](https://tex.z-dn.net/?f=x%20%2B%205y%20-%202z%20%2B%2014%20%3D%200)
