Answer:
16
Step-by-step explanation
6 = x/4 + 2
subtract 2 from both sides
4 = x/ 4
since its dividing x and 4 you need to multiply 4 on both sides
16 = x
Answer:
x < −

On the graph, you would put an open dot on -5 and an arrow continuing down it
Answer:
See below
Explanation:
You multiply 8 and 6.9
To get 55.2 ounces
Diameter = 8 yards so the Radius = 4 yards:
Area of a sphere = 4π.R² and hemisphere = 2π.R²
Area of hemisphere = 2.π.(4)² = 32.π
But note we didn't calculate yet the are that closes this hemisphere:
Area of the cicle = π.R² = π.(4)² = 16.π, so the surface area of the hemisphere is 32π + 16π = 48.π (Or =150.8 yard²)
