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/kg. Find the number of kg of brand X sugar and brand Y sugar required to make 40 kg of generic sugar.

Answers

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

Answers

Answer:

382. 5

Step-by-step explanation:

Answer:

26.74 ($) or change currency sign to suit.

Step-by-step explanation:

Binoculars Mark up = 10x 1.45 = 14.50

Sales tax = 14.5 x 1.085 = 15.7325

Total cost per Binocular = 15.73 ($,)

Bird Guide Mark up = 7 x 1.45 = 10.15

Sales Tax  = 10.15 x 1.085 = 11.01275

Total cost per Bird Guide = 11.01 ($)

One of each is found by addition.

15.73 + 11.01 = 26.74 ($) or change currency sign to suit.

We know that a square is made-up of four equivalent sides, and four right angles. So, by process of elimination, you are left with the top one.

Another way of getting the same answer is we know that the only quadrealateral with four equivalent sides is a square, so the top answer is correct.

Now if we added 1+-20 would be -19. We would need exactly 20+-20 to get out of the negitives.
