Answer:
Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail is T.
Step-by-step explanation:
It is given that V(d) models Erica's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail.
We need to find the meaning of V(2)=T.
On comparing V(d) and V(2), we get d=2.
Since V(d) models Erica's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail, therefore V(2) models Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail.
It means Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail is T.
Subtract 5x from both sides. in standard form, the equation is:
-3y - 5x = 21
Firstly, the order of operations is as follows: PEMDAS or parentheses, exponents, multiplication, division, addition, then subtraction.
All of these are done in the exact order given above.
For example, given the equation (4 x 7) + (6 / 2) - 3^2 = ?
1. Parentheses
- Solve the equations within the parentheses first.
(4 x 7) + (6 / 2) - 3^2 = 28 + 3 - 3^2
2. Exponents
- Second, if there are any exponents, solve this.
28 + 3 - 3^2 = 28 + 3 - 9
3. Mulltiplication
4. Division
5. Addition
28 + 3 - 9 = 31 - 9
6. Subtraction
31 - 9 = 22
Answer: 22.
