Answer:

1.425.

Step-by-step explanation:

1 .425 is the only one which can be written as a fraction ( 1425/ 1000).

π is a non repeating decimal which goes on without bounds.

So is √50 (try entering it on your calculator).

√-4 : there is no real number whose square root is negative.

The answer to your question would be "B"

1.425

Rational numbers are numbers that can be turned into a fraction. Decimals, fractions, and integers are rational numbers.

"A" would be incorrect because there is no way to write $\pi$ as a simple fraction.

"C" would be incorrect because the square root of 50 is not a perfect square.

"D" would also be incorrect because it can not be turned into a fraction.

Generic sugar which costs $2.23/kg is made by combining brand X sugar which costs $1.18/kg with brand Y sugar which costs $3.98/

White raven [17]

Answer:

X = 14 kg

Y= 7 kg

Step-by-step explanation:

LET X and Y equal the amounts of brand X and Y

X = kg of brand X

Y = kg of brand Y

we know:

1) X + Y = 21 (kg)

2) 1X + 4Y = 2(X + Y) (This is the cost/kg * amounts for total cost)

Coefficients 1,4,2 are the cost/kg)

substitute eq. 1 (X+Y), = 21 into right side of equation 2

1X + 4Y = (21)*2

use elimination to solve 2 equations

X + Y = 21

X + 4Y = 42 (now subtract, note: I wrote the 1X as just X)

------------------

0 -3Y = -21 OR Y = 7 kg so X = (21-7) OR X = 14 kg
