Answer :
8 _ _ _ _ _ 5
x _ _ _ _ _ 15
8 / x = 5 / 15 ;
x = ( 8 × 15 ) / 5 ;
x = 120 / 5 ;
x = 24 ;
x _ _ _ _ _ 15
8 / x = 5 / 15 ;
x = ( 8 × 15 ) / 5 ;
x = 120 / 5 ;
x = 24 ;
y = kx
Plug in what we know:
5 = k(8)
5 = 8k
Divide 8 to both sides:
k = 0.625
Plug this back into the equation along with y = 15:
y = kx
15 = 0.625x
Divide 0.625 to both sides:
x = 24
Plug in what we know:
5 = k(8)
5 = 8k
Divide 8 to both sides:
k = 0.625
Plug this back into the equation along with y = 15:
y = kx
15 = 0.625x
Divide 0.625 to both sides:
x = 24
