Answer:
its the first one. you're right.
A reflection over y-axis.
Answer:
80
Step-by-step explanation:
10 divided by 1/8 is equal to 10 times 8
(its called recipical)
The solution to the equations is x=20 and y=40
Step-by-step explanation:
Let,
Small tier = x
Medium tier = y
According to given statement;
1.The situation with a system of equations.
3x+y = 100 Eqn 1
3x+2y=140 Eqn 2
2. Solving the System of equations;
![Subtracting\ Eqn\ 1\ from\ Eqn\ 2\\(3x+2y)-(3x+y)=140-100\\3x+2y-3x-y=40\\y=40\\Putting\ value\ of\ y\ in\ Eqn 1;\\3x+40=100\\3x=100-40\\3x=60\\Dividing\ both\ sides\ by\ 3\\\frac{3x}{3}=\frac{60}{3}\\x=20](https://tex.z-dn.net/?f=Subtracting%5C%20Eqn%5C%201%5C%20from%5C%20Eqn%5C%202%5C%5C%283x%2B2y%29-%283x%2By%29%3D140-100%5C%5C3x%2B2y-3x-y%3D40%5C%5Cy%3D40%5C%5CPutting%5C%20value%5C%20of%5C%20y%5C%20in%5C%20Eqn%201%3B%5C%5C3x%2B40%3D100%5C%5C3x%3D100-40%5C%5C3x%3D60%5C%5CDividing%5C%20both%5C%20sides%5C%20by%5C%203%5C%5C%5Cfrac%7B3x%7D%7B3%7D%3D%5Cfrac%7B60%7D%7B3%7D%5C%5Cx%3D20)
