Since 2.5 is a quarter of 10, u have to find a quarter of 16 which is 4. So X=4
isyllus

Answer:

x = 4

Step-by-step explanation:

If x varies directly with y

Directly Proportional:

[tex]y\proto x[/tex]

[tex]y=kx[/tex]

where, k is constant of proportionality

x = 2.5 when y = 10

[tex]10=k\cdot 2.5[/tex]

[tex]k=4[/tex]

Equation:

y=4x

Put y=16 and solve for x

[tex]16=4x[/tex]

[tex]x=4[/tex]

Hence, The value of x is 4 at y=16
