approximately 9 out of 10 smokers began smoking before the age of 21. In a group of 400 smokers, about how many of them started

Slav-nsk [51]

Greetings!

You can create an equation to solve for x:
$9/10=x/400$
Cross Multiply.
$9*400=10*x$
$3600=10x$
Divide both sides by 10.
$(3600)/10=(10x)/10$
The Answer Is:
$360=x$

Out the 400 smokers, approximately 360 of them started smoking before age 21.

Hope this helps.

X= r-h/y<br> solve for h and r

malfutka [58]

X = r - h/y ; Solve for h & r

Let's first solve for h :)

Add h/y to both sides.

h/y + x = r

So, r = h/y + x

Now, let's solve for h.

x = r-h/y

Subtract r from both sides.

-r + x = -h/y

Multiply both sides by y.

y(-r + x) = y(-h/y)

Simplify.

-ry + xy = -h

Divide both sides by -1.

ry - xy = h

So, h = ry - xy
