Answer:
x=11, y=2
Step-by-step explanation:
We can set 1 equal to x-5y and then solve for x. and y. 
x = 5y+1
y = x-1/5
We can use this information and plug back in the values for 3y-x or x-5y. 
We can set -3 = 3y-x or 1 = x-5y. 
To solve for x using -3 = 3y-x we can swap the values of x and y which would make it -3 = 3(x-1/5)-5(x-1/5)+1. 
We can do a bit of algebra which would get us x = 11. 
Knowing that y = x-1/5 we can plug in 11 for x. y = 11-1/5. 
y=2
x=11, y=2
 
        
             
        
        
        
Answer:
d=54
Step-by-step explanation:
22 + 15 = d - 17
37=d-17
54=d
d=54

For this case we have the following equation:
 s = 300 / d
 Where,
 s: the speed of the current in a certain whirlpool
 d: the distance from the center of the whirlpool
 We have then that:
 If the distance from the center of the whirpool is large, the speed is small.
 If the distance from the center of the whirlpool is very small, the speed tends to infinity
 Answer:
 Large distance, small speed.
 Short distance, speed tends to infinity.

This triangle is a right angled triangle as we can see ∠POC, has a right angled sign. Now, we will assume the missing angle to be x, thus, 
25° + 90° + x = 180° ( Angle sum property of a triangle ) 
115° + x = 180° 
x = 180° - 115°
x = 65°
Thus, the measure of missing angle is 65°.
Hope that helps. :D
