Answer:
x = 2
y = -3
z = 4
( 2 , -3, 4 )
Step-by-step explanation:
x + y + z = 3 ---- i 
x – y =5 ---- ii
y - z = -7 ---- iii
ii + iii
x - z = -2 ---- iv
i + ii
2x + z = 8 --- v
iv + v 
3x = 6
x = 2
x=2 substitute for v 
z = 4
x =2 substitute for ii
y = -3
 
        
             
        
        
        
Answer:
A = π · (r²)
Step-by-step explanation:
 π · r² is the area of a circle.
π · r² is the area of a circle. 
While π · r² · h can also give you the radius, it can only do so for the Volume  , not the Area
, not the Area  .
.
 doesn't really apply for a circular object, as it requires the length and width. For circular objects, both are equal to the diameter of the object, and 2² · r² · h does not equal the Volume.

Ok is easy first it takes 10mm =1cm 100cm=1m 1000mm=1km so you do 1.5 divided by 1000km=.0015 km so your answer is .0015km
