Answer:

Let x represent the number from the sentence.

Step-by-step explanation:

2(x) + 2(1/x) = 20/3

2x + 2/x = 20/3

multiply both sides of the equation by 3x

6x + 6 = 20x

6x - 20x + 6 = 0

6x - 18x - 2x + 6 = 0

6x(x-3 -2(x-3) = 0

(6x-2 = 0 or x-3 = 0

6x = 2 or x = 3

x = 2/6

x = 1/3

Since x represented the number

Therefore x = 1/3 or 3

Papessa [141]

Answer:

The system of linear equations are $y=5+x$ and $x+y=25$

Step-by-step explanation:

Given : The number of students who chose lunch was 5 more than the number of students who chose breakfast. Let x represent the number of students who chose breakfast and y represent the number of students who chose lunch.

(50 students picked, 25 picked dinner the rest picked lunch and breakfast)

To find : Write a system of linear equations that represents the numbers of students who chose breakfast and lunch ?

Solution :

The number of students who chose breakfast be 'x'

The number of students who chose lunch be 'y'.

The number of students who chose lunch was 5 more than the number of students who chose breakfast.

i.e. $y=5+x$

Now, Total student were 50 and 25 picked dinner the rest picked lunch and breakfast i.e. 25.

So, $x+y=25$

Therefore, the system of linear equations are $y=5+x$ and $x+y=25$

PLEASE HELP ME ...........Julie was looking at the architect's blueprint of her house. The scale on blueprint was 1/4 inch = 1 f

MAVERICK [17]

Answer:

On the blueprint the dimensions are 48 inches by 64 inches.

Step-by-step explanation:

Given:

The scale on blueprint was 1/4 inch = 1 foot.

The actual dimensions of her bedroom are 12 feet by 16 feet.

Now, to find the dimensions on the blueprint.

Let the dimensions on the blueprint be $x$ by $y.$

As, given the scale on blueprint:

$\frac{1}{4}\ inch=1\ foot$

So, $\frac{1}{4}\ inch$ is equivalent to 1 foot.

Thus, $x$ is equivalent to 12 feet.

And, $y$ is equivalent to 16 feet.

Now, solving by cross multiplication method:

$\frac{\frac{1}{4}}{1} = \frac{x}{12}$

$\frac{4}{1} =\frac{x}{12}$

By cross multiplying we get:

$48=x$

$x=48\ inches.$

Now, again:

$\frac{\frac{1}{4}}{1} =\frac{y}{16}$

$\frac{4}{1} =\frac{y}{16}$

By cross multiplying we get:

$64=y$

$y=64\ inches.$

Therefore, on the blueprint the dimensions are 48 inches by 64 inches.
