Answer: 5n = 3d and 3n + 6 = 2d + 4

Given that the numerator and denominator of a fraction are in the ratio of 3 to 5. When the numerator and denominator are both increased by 2, the fraction is equal to \dfrac{2}{3}.  

We are to select the system of equations that could be used to solve the problem.  

Since n denotes the numerator and m denotes the denominator of the given fraction, so we have:

n/d = 3/5

5n = 3d

<h3>and</h3>

(n+2)/(d+2) = 2/3

3(n+2) = 2(d+2)

3n + 6 = 2d + 4

Thus, the required system of equations is,

5n = 3d and 3n + 6 = 2d + 4

Brainliest pweaseee if the answer is clear and correct! <3 ~~~

Use the algebra tiles to model the equation 2x + 4 = 3x + (−1). Then complete the sentences. To model 2x + 4, you need:
melomori [17]

The value of x would be 5 for the model 2x+4.

Rearrange unknown terms to the left side of the equation,
= > 2x-3x = -1 - 4

Combine like terms= -x = -1-4

By calculating the sum or difference : -x = -5

Lets divide both sides of the equation by the resulting coefficient 5
So x = 5

P: Price of soda

5×2(S×P)

but if each sized sodas cost a different amount it would be

S: Price of first size
S2: Price of second size
S3: Price of third size
and so on.

5×2(S+S2+S3...)

but if they all together bought 2 of EACH size soda, then it is.

2(S×P)

but if each sized sodas cost a different amount it would be

S: Price of first size
S2: Price of second size
S3: Price of third size
and so on.

yKpoI14uk [10]

Answer:

Should he be surprised at this result

The found proportion is 1.56 standart deviations away from the expected. we should no be surprised .

Step-by-step explanation:

p=0,44

q=1-0.44=0.56

u=p=0,44

o=\sqrt{pq/n}=\sqrt{(0.44)(0.56)/244} = 0.032

proportion of students in binge drinking 96/244 = 0.39

The found proportion is 1.56 standart deviations away from the expected. we should no be surprised .
