d) 9
Step-by-step explanation:
In a kite, the two shorter sides have to be equal.
Therefore
3x-5 = 22
Add 5 to each side
3x-5+5 = 22+5
3x = 27
Divide each side by 3
3x/3 = 27/3
x =9
Answer:
target speed for the marathon has been achieved and exceeded
Step-by-step explanation:
Given that :
Target speed = 25 mph
Current speed = 15 miles in 1/2 an hour
Current speed :
15 miles in 0.5 hours
X miles in 1 hour
0.5x = 15 miles
X = 15 / 0.5
X = 30 miles per hour
Hence, current speed in miles per hour = 30mph
This means that her target speed for the marathon has been achieved and exceeded
