Answer:

Let the no. Of students from Indiana be x

Let the no. Of students from the rest of the country and abroad be y

x = 3y (Given) (i)

x + y = 884 (Given) (ii)

Subtract equation (ii) from 1

x -3y = 0

-(x+y = 884)

-4y = -884

Therefore y = 221

Therefore no. Of students from the rest of the country and abroad is 221

Substituting the value of y in (i)

x = 3 x 221

Therefore x = 663

Therefore no. Of students from Indiana is 663

Hope this helps!

For which value(s) of x will the rational expression below equal zero? Check all that apply.
geniusboy [140]

Answer:

x = 5 and -2

Step-by-step explanation:

Given the function of x to be;

f(x) = (x-5)(x+2)/x+1

The value of x that will make the function zero can be calculated for by equating the given function to zero first to have;

If f(x) = 0, then;

(x-5)(x+2)/x+1 = 0

Cross multiplying;

(x-5)(x+2) = 0

(x-5) = 0 and x+2 = 0

x = 5 and x = -2

The value of x that will make the function zero is therefore 5 and -2
