Answer:
Equation is [tex]x=\frac{1}{2}yz[/tex] and when y=2 and z=4, x will be 4.
Step-by-step explanation:
Given:
x varies jointly with y and z.
It also means x is directly proportional to y and z.
[tex]x=2, y =4,z=1[/tex]
From above values we can compute the equation as.
[tex]x=\frac{1}{2}yz\\2= \frac{1}{2} \times 4 \times 1\\2=2[/tex]
Hence the Equation is [tex]x=\frac{1}{2}yz[/tex]
Now y=2 and z=4 we get.
[tex]x=\frac{1}{2}\times 2 \times 4= 4[/tex]
Hence when y=2 and z=4, x will be 4.
