Fantom [35]
Their momentum would be equal. so, 
m1v1 = m2v2
0.25 * v1 = 0.05 * 500
v1 = 25 / 0.25
v1 = 100 m/s

In short, Your Answer would be 100 m/s

Log 15 = log(7 - 4x)​
Korvikt [17]

Answer:

x =-2

Step-by-step explanation:

log 15 = log(7 - 4x)​

The terms inside the log functions must be the same

15 = 7 -4x

Subtract 7 from each side

15-7 = 7-4x-7

8 = -4x

Divide  each side by -4

8/-4 =-4x/-4

-2 =x
