1600m = 1600 ÷ 1000 = 1.6 km
Answer: 1.6 km
Answer:
No solutions
Explanation:
The given system of equations is
2y = x + 9
3x - 6y = -15
To solve the system, we first need to solve the first equation for x, so
2y = x + 9
2y - 9 = x + 9 - 9
2y - 9 = x
Then, replace x = 2y - 9 on the second equation
3x - 6y = -15
3(2y - 9) - 6y = -15
3(2y) + 3(-9) - 6y = -15
6y - 27 - 6y = -15
-27 = -15
Since -27 is not equal to -15, we get that this system of equation doesn't have solutions.
Which one is prime number 2, 3, 5, 7, 13, 14, 15, 23, 25, 29, 30, 36, 61

2,3,5,7,13,15,23,and 61 are all prime
Answer:
42
Step-by-step explanation:
x = Ky
18 = K(3)
K = 18/3 = 6
x = 6y
x = 6(7) = 42
