Answer:

Step-by-step explanation:

Known facts:

  • the ratio of mass potatoes to the mass of carrots is 5:2
  • the mass of potato is 9kg more than the mass of carrot

Let us set up the equation:

  • variables: mass of potatoes: p, the mass of carrots: c

p/c = 5/2 --> 2p = 5c --> 2p -5c = 0 -- equation 1

p = 9 + c --> p - c = 9 -- equation 2

Multiple equation 2 by 2

2p - 2c = 18 -- equation 3

subtract equation 1 and equation 3

-3c = -18

c = 6, so p = 15

So the total mass of both ingredients is 21 kg

What’s the equivalent of 50000
dezoksy [38]

Is this for money? Do you want an equivalent fraction? Please be more specific, but I'll imply a couple of options.

FOR MONEY:

50,000 euros is 55142.50 dollars

50,000 dollars is 45337.08 euros

Is 50,000 US dollars a good salary? In my opinion, yes. If you are a single person, and you work an office job from 9 to 5, then yes, that is a good salary.

MATH/NUMBERS:

50,000 = 100,000 ÷ 2

50,000 = 200,000 ÷ 4

50,000 = 25,000 × 2

50,000 = 12,500 × 4

There are other examples that could be used for both money and math, but I would not be able/do not have the time to list them all.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I hope this helps!
