Sagot :
Answer:
y=0.8
x=0.4
Explanation:
Let x and y be the two unknown decimal numbers
xy=0.32
[tex]x=\frac{1}{2} y[/tex]
Substitute the value of x
([tex]\frac{1}{2} y[/tex])(y)=0.32
[tex]\frac{1}{2} y^{2}[/tex]=0.32
[tex]y^{2}[/tex]=0.64
y=0.8
x= [tex]\frac{1}{2} (0.8)[/tex]
x=0.4
Answer:x=0.8;y=0.4
Step-by-step explanation:
x*y=0.32
y=0.5x
x(0.5x)=0.32
0.5x^2=0.32
x^2=0.32/0.5=0.64
x=0.8
checking
xy=0.32
(0.8)[(0.5)(0.8)]=0.32
(0.8)(0.4)=0.32
0.32=0.32
