Answer:

Equation: 3(x+5)=60

Solution: 15 inches

Step-by-step explanation:

Let x represent the original side length of the equilateral triangle. Then, the new length of each side is x+5. Because a triangle has three sides, the new perimeter is 3(x+5), which is 60 inches. Dividing both sides by 3, we get that x+5=20, so x=15.

Wilbur landed his plane.
lora16 [44]

Answer: 1,700\ seconds

Step-by-step explanation:

Observe the graph provided in the exercise.

The y-axis represents the plane's elevation in meters and the x-axis represents the time in seconds.

Notice that at 0 seconds the elevation of the plane is 8,500\ meters. Based on the graph, each 200\ seconds the elevation of the plane decreases 1,000\ meters.

The plane lands when the elevation is 0 meters and this happens when the line shown in the graph intersects the x-axis.

Therefore, the time took the plane to land is:1,700\ seconds
