There are 16 red shirts and some black shirts hanging in the store. the ratio of the number of red shirts to that of black shirts is 2: 3. if 5 red shirts are added into the box, what is the new ratio?

If 5 red shirts are added into the box,    7 : 8  is the new ratio.

Step-by-step explanation:

The number of red shirts =  16

Let the number of black shirts = k

Now as the ratio of Red Shirts : Black Shirt = 2 : 3

By RATIO OF PROPORTIONALITY:

⇒

or,

Hence, the number of Black Shirts in the Store = 24

Now, new number pf red shirts = 16 + 5 = 21

So, by the proportionality again,  ratio is

Hence, the new ratio of Red shirts : Black Shirts =  7 : 8

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
