Andre45 [30]

Answer:

$y(x) = 9 + 0.25*(18 - x)$

Step-by-step explanation:

We have the following variables:

y: hours of sleep

x: age

Each day, a young person should sleep 9 hours

This means that y is 9 added to something

plus 1 4 hour for each year that the person is under 18 years of age.

For each year the person is under 18 years of age, she should sleep 1/4 = 0.25h on top of the 9 hours.

So the equation relating hours of sleep y and age x is:

$y(x) = 9 + 0.25*(18 - x)$

If the expression 2x/a plus b = c is solved for x in terms of a, b, and c, then x = what?

Doss [256]

Answer:

The value of x in terms of a, b ans c is $x=\frac{ac-ab}{2}$

Step-by-step explanation:

We have given the expression $\frac{2x}{a}+b=c$

We have to find the value of x in terms of a, b and c

So $\frac{2x}{a}+b=c$

$\frac{2x}{a}=c-b$

$2x=a(c-b)$

$2x=ac-ab$

$x=\frac{ac-ab}{2}$

So the value of x in terms a ,b and c is $x=\frac{ac-ab}{2}$
