t = 15 + x and t = 5 + 2x represents the system of equations for this real world situation

Solution:

Workout Gym has a sign up fee of $15 and charges $1 per day for membership

Therefore,

Charge per day = $ 1

Let "x" be the number of days charged for membership

Let "t" be the total charge for membership

Thus, we frame a equation as:

Total fee = sign up fee + charge per day (number of days)

Total fee = 15 + 1(x)

t = 15 + x ------- eqn 1

Healthy Gym has a $5 sign up fee and charges a $2 daily fee

Charge per day = $ 2

Let "x" be the number of days charged for membership

Let "t" be the total charge for membership

Thus, we frame a equation as:

Total fee = sign up fee + charge per day (number of days)

t = 5 + 2(x)

t = 5 + 2x ------- eqn 2

Thus eqn 1 and eqn 2 represent the system of equations for this situation

The ratio of the numerator to the denominator of a fraction is 2 to 3. If both the numerator and the denominator are increased b

masha68 [24]

Answer:

The fraction is $\frac{4}{6}$

Option (B) is correct.

$3n-2d=0$ and $4n+8=3d+6$

Step-by-step explanation:

Let n denotes numerator and d denotes denominator of the fraction.

Given : The ratio of the numerator to the denominator of a fraction is 2 to 3.

That is $\frac{n}{d}=\frac{2}{3}$

Cross multiply , we get,

$3n=2d$

Or, $3n-2d=0$ ........(1)

Also, given : . If both the numerator and the denominator are increased by 2, the fraction becomes 3/4

That is $\frac{n+2}{d+2}=\frac{3}{4}$

Cross multiply , We get,

$4{n+2}={3}{d+2}$

$4n+8=3d+6$ .........(2)

$3d-4n=2$ .......(3)

Thus, from (1) and (2) , option (B) follows.

Solving equation (1) and (3) to get the original fraction using elimination method,

3n - 2d = 0 ............(1)

and 3d - 4n = 2 .........(3)

Multiply equation (1) by 3 , we get ,

9n - 6d = 0 ..........(4)

Multiply equation (3) by 2 , we get ,

-8n + 6d = 4 ..........(5)

Adding (4) and (5) , we get,

9n - 6d -8n + 6d = 4 + 0

⇒ n = 4

Put n = 4 in (1), we get

3n - 2d = 0 ⇒ 3(4) - 2d = 0 ⇒ 12 -2d = 0 ⇒ 12 = 2d ⇒ d = 6

so, the numerator is 4 and the denominator is 6.

Thus, the fraction is $\frac{4}{6}$
