Answer:
16/13 is the answer.
26-10 is 16 and 2x5+3 is 13
Rate =distance/time
:)
it's the famous d=r*t (distance is rate multiply by time)
therefore, changing the way of expressing the equation d/t =r you can use it to find r
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.
we can start off by multiplying both sides by the LCD of all fractions, in this case that'd be 3.
6*1 = 6
Next...
1/10 = 10% which equals 0.1
0.1 * 9 = 0.9
Now...
1/100 =1% which equals 0.01
So that means that 0.01 * 8 = 0.08
Lastly... 0.0010 * 3 = 0.003
You add
6 + 0.10 + 0.08 + 0.003 and you get 6.183.... (Kevin’s distance) which is obviously a farther distance than 6.093.
Kevin is correct :)
