Sveta_85 [38]

Answer:

y-\frac{1}{3}+y=1000

x=499.83

y=500.16

Step-by-step explanation:

We can solve this problem with a system of equations:

The total quantity of Nerds in the box:

x+y=1000 (1)

The amount of Nerds left in the box: y  

The number of portions Mrs. Konings has taken: x  

The amount of Nerds left in the box decreases by a third each time she dumps out a portion:

x=y-\frac{1}{3} (2)

Substituting (2) in (1):

y-\frac{1}{3}+y=1000 (3) This is the equation

Let's find y:

y=\frac{3001}{6}=500.16 (4)

Now let's find x by substituting (4) in (2):

x=500.16-\frac{1}{3}=499.83 (5)

The difference between two natural numbers is 39. If the larger number is divided by the smaller one, then the quotient is 3 and
mr_godi [17]
-------------------------------------------
Define x and y :
-------------------------------------------
Let one number be x and the other number will be x + 39

-------------------------------------------
Construct equation : 
-------------------------------------------
When the big number divided by the smaller number, the quotient is 3 with 11 remaining
⇒ \dfrac{x + 39 - 11}{x} = 3

-------------------------------------------
Solve x :
-------------------------------------------
\dfrac{x + 39 - 11}{x} = 3

\dfrac{x + 28}{x}  = 3

x + 28 = 3x

2x = 28

x = 14

-----------------------------
Find the numbers:
-----------------------------
small number = x = 14

big number = x + 39 = 14 + 39 = 53

-------------------------------------------
Answer: The smaller number is 14.
