Y= 1/2x+ 2 to make the x the subject.

Answer:

$x=2y-4$

Step-by-step explanation:

$y=\frac{1}{2} x+2$

"To make x the subject" means to have the equation with all the terms in x on one side. As of now, y is the subject of the equation.

You start by subtracting 2 from both sides, you should get the following.

$y-2=\frac{1}{2} x$

Then you multiply by 2 from both sides, you should end up with the following.

$2(y-2)=x$

Therefore, you get the following.

$x=2(y-2)$

Finally, you distribute and get the answer.

$x=2y-4$

Answer:

110 students walk or bike to school.

Step-by-step explanation:

48% of the 208 students walk, whereas 5% bike. Combining 48% and 5%, we get 53%.

53% of the total number, n, comes to 208 students.

This number is 0.53(208 students), or 110 students.
