This is the concept of scale factors, given that the length of the model which has been modeled by scale factor 1/64 is 0.39 inches, then the actual diameter will be:
scale scale factor=(model diameter)/(actual diameter)
where:
actual diameter=(model diameter)/(scale factor)
=0.39/(1/64)
=24.96 inches
Given :
Two equations :
-8x + 3y = -17 ....1)
3x - y = 7 ....2)
To Find :
The solution of the system.
Solution :
Multiplying equation 2) by 3 and adding with equation 1), we get :
(-8x + 3y) + 3(3x - y) = -17 + 21
x = 4
Putting above value of x equation 2) we get :
12 - y = 7
y = 5
Therefore, solution of system is ( 4,5 ).
