Answer: 9.25

Step-by-step explanation:

Given equation : [tex]5x + 2y = 20[/tex]

To find the value of y at x= 0.3, we need to first substitute the value of x= 0.3 in the given equation.

Now, Substitute x= 0.3 in given equation, we get

[tex]5(0.3) + 2y = 20\\\\\Rightarrow\ 1.5+2y=20[/tex]

Subtract 1.5 from both sides .

[tex]2y=18.5[/tex]

Divide both sides by 2 .

[tex]y=9.25[/tex]

Hence, the value of y= 9.25
