Answer:
2.5 hours
Step-by-step explanation:
To calculate the time taken to travel the distance, we will apply the distance speed time formula, which links the speed of an object, the distance traveled by it and the time taken for it to travel the distance as follows:
Time taken to travel the distance = Distance Traveled / Average Speed
We know the average speed to be 7 km/h
and the total distance traveled to be 17.5 km
Using these values and putting them in the equation we get,
Time taken = 17.5 / 7 = 2.5

Answer:
6.63 cm
Step-by-step explanation:
The segments within the circle form a right angle. Triangle CRS as a right triangle must follow the Pythagorean theorem which says the square of each leg adds to the square of the hypotenuse.
a² + b² = c²
Here a is unknown, b = 10 and c = 12.
a² + 10² = 12²
a² + 100 = 144
a² = 44
a = √44 = 6.63
Answer: -4
Step-by-step explanation: Hello! :) To get started we need to use the equation 7x+3=4x-9, First, we need to subtract 4x from both sides to get 3x+3=-9, then we need to subtract 3 on both sides to get 3x=-12, Finally, we need to divide both sides by 3 to get x = -4. So x = -4.

13x-9=16
+9 +9
13x= 25
---- -----
13x 13x
x=1.92
Add nine to both sides of equation to cancel out the negative nine. Then, divide both sides by 13, which will result in the answer listed above.
