Answer:
Combine like terms
Step-by-step explanation:
2 over 3 plus 5 equals 5 and 2 over 3
Based on our conversation above, we can then easily find the missing x-coordinate. If the equation for line BC is y = 6*x - 11 and we know that the y-coordinate is 13, then
13 = 6*x - 11
24 = 6*x
4 = x
The x-coordinate is 4.

Answer:
320 ft² (nearest whole number)
Step-by-step explanation:
Given:
- height of fence post = 8 ft
- diameter of fence post = 1 ft ⇒ radius = 0.5 ft
- total number of posts = 12
- π = 3.14
Surface area of a cylinder = 2πr² + 2πrh
⇒ SA of one fence post = 2 · 3.14 · 0.5² + 2 · 3.14 · 0.5 · 8
= 1.57 + 25.12
= 26.69 ft²
As there are 12 fence posts,
Total paint needed = 12 × 26.69
= 320.28 ft²
= 320 ft² (nearest whole number)
