Ohhh I don’t know Plss like hahaha chariot
The question is incomplete, here is the complete question:
You and your friend are selling magazine subscriptions. You sell 8 fewer magazine subscriptions than your friend. Together you sell 42 magazine subscriptions. Write a system of linear equations that represents this situation.
The system of linear equations that represents this situation is:
x + y = 42
x - y = 8
Step-by-step explanation:
To solve the problem assume that
- x represent the number of magazine subscriptions that your friend sell
- y represents the number of magazine subscriptions that you sell
∵ Your friend sells x magazine subscriptions
∵ You sell y magazine subscriptions
∵ Together you sell 42 magazine subscriptions
∴ x + y = 42 ⇒ (1)
∵ You sell 8 fewer magazine subscriptions than your friend
∵ Your friend sells x magazine subscriptions
∵ You sell y magazine subscriptions
- That means y = x - 8
∴ y = x - 8
- Add 8 for both sides
∴ 8 + y = x
- Subtract y from both sides
∴ 8 = x - y
- Switch the two sides
∴ x - y = 8 ⇒ (2)
The system of linear equations that represents this situation is:
x + y = 42
x - y = 8

Answer:
-2
Step-by-step explanation:
8-(-2) = 8 + 2 = 10
7 - 12 = -5
10 / -5 = -2
Answer:
x = 10.19803903 meters
Step-by-step explanation:
First, you need to calculate the differences in the posts height.
8 - 6 = 2
Then you can use that to draw a right triangle and solve for the distance between the tops using Pythagorean theorem.
10² + 2² = x²
100 + 4 = x² --- solve
x² = 104 --- solve
x = 10.19803903 meters --- square root both sides
