Y=(8)/(3-x) solve for x. The 8 is over 3-x, it is a fraction.
chubhunter [2.5K]

Answer:

x = -(8 - 3 y)/y

Step-by-step explanation:

Solve for x:

y = 8/(3 - x)

y = 8/(3 - x) is equivalent to 8/(3 - x) = y:

8/(3 - x) = y

Take the reciprocal of both sides:

(3 - x)/8 = 1/y

Multiply both sides by 8:

3 - x = 8/y

Subtract 3 from both sides:

-x = (8 - 3 y)/y

Multiply both sides by -1:

Answer:  x = -(8 - 3 y)/y

What is the diameter of this circle if the circumference is 30 x inches?
ch4aika [34]

Answer:

<h2>10 inches</h2>

Step-by-step explanation:

Given the circumference= 30 in

we know that the formula for circumference is

C= 2\pi r

30= 2*3.142*r\\\\r= \frac{30}{2*3.142} \\\r= \frac{30}{6.248}\\\r= 4.77 in

The diameter is 2*r= 4.77*2=9.55 in

Approximately the diameter is 10 inches
