Answer:

x=1 y=3/4 there are many values possible since there is no exact clbalue given

Step-by-step explanation:

if we letx to be 1 then 2+3y=5-y then we arrange all terms we get y to be 3/4

you can put any value of x since the question has'nt given us

Is 5.731 an rational number and integer or whole number

Delicious77 [7]

Answer:

<h3>Rational number</h3>

Step-by-step explanation:

A rational number are number that can be written as the ratio of two integers. Integers are whole numbers and they can be positive or negative including zero.

Looking at the value 5.371, we can write it in fraction form as shown;

5.371 = 5371/1000

Since 5.371 is equivalent to 5371/1000 and 5371/1000 is a ratio of two integers 5371 and 1000 therefore we can conclude that 5.731 is a rational number

Note that decimal numbers are not integers and are not whole numbers.

Graph the function y = 4 . Then use the graph to find the missing x- or y-coordinates for the function to the nearest hundredth.

Elodia [21]

Given equation is y=4.

Question says to graph the given equation y=4 then use the graph to find the missing x- or y-coordinates for the function to the nearest hundredth.

Equation y=4 has no "x" so that means line y=4 will be a horizontal line which passes through 4 on y-axis.

Since it is parallel to x-axis so that means there is no x-intercept.

y-intercept is (0,4) as the line crosses at 4 on y-axis.

Helppp this is my math test Which model is 85% shaded?

Anettt [7]

Answer:

Model 1 represents 85% shaded area.

Step-by-step explanation:

Here, each model consists of equal sized rectangles.

Please refer to attached figure to know the model number.

Model 2 (on top right of question figure) contains a total of 20 such rectangles out of which 13 are shaded. As per formula of percentage:

$\text{Percentage of shaded area} = \dfrac{\text{Number of shaded rectangles}}{\text{Total number of rectangles}} \times 100\\\Rightarrow \dfrac{13}{20}\times 100 = 65\%$

Model 3 (on bottom left of question figure) contains a total of 16 such rectangles out of which 10 are shaded. As per formula of percentage:

$\text{Percentage of shaded area} = \dfrac{10}{16}\times 100 = 62.5\%$

Model 4 (on bottom right of question figure) contains a total of 16 such rectangles out of which 13 are shaded. As per formula of percentage:

$\text{Percentage of shaded area} = \dfrac{13}{16}\times 100 = 81.25\%$

Model 1 (on top left of question figure) contains a total of 20 such rectangles out of which 17 are shaded. As per formula of percentage:

$\text{Percentage of shaded area} = \dfrac{17}{20}\times 100 = 85\%$

Hence, model 1 is the correct answer.

How do you write an equation to represent a real-world situation?

Maurinko [17]

You have to organize the parameters of the real-world situation that is known and unknown. Also, you have to distinguish which of them are dependent and independent. Next, you assign letters as your variables. Lastly, you make an algebraic expression by translating the relationship into the mathematics.

Mallory needs to go to the airport. It takes her 120 minutes to get there by car. This is 3 times the time it takes by

seraphim [82]

It will take Mallory 40 minutes to get to the airport by train.

Step-by-step explanation:

Given,

Time taken by car = 120 minutes

Time taken by train = t

According to given statement;

Time taken by car = 3 times time taken by train

$120=3t$

Dividing both sides by 3

$\frac{120}{3}=\frac{3t}{3}\\40=t\\t=40$

It will take Mallory 40 minutes to get to the airport by train.
