C). 6*6√2*12 is your answer.... i think
Answer:
The better buy is to buy 10 kilograms of potatoes at $ 3.92, since each kilogram costs $ 0.392.
Step-by-step explanation:
To find the cost per unit in each case and then state which is the better buy, the following calculations must be performed:
6kg of potatoes for $ 2.45:
2.45 / 6 = 0.408
15 kg of potatoes for $ 5.9:
5.90 / 15 = 0.393
10 kg of potatoes for $ 3.92:
3.92 / 10 = 0.392
Thus, the better buy is to buy 10 kilograms of potatoes at $ 3.92, since each kilogram costs $ 0.392.
8x9=72
exponent 7 stays same
Answer:
72^7
10x-9y=46. Equation 1
-2x+3y=10. Equation 2
Equation 2 should be multiplied by 3
-6x+9y=30
So,
By eliminating y component we get,
4x=56
X=14.
Substitute in equation 1.
Y=1.444.
Hope it helped you
