The answer is 24/12. Then you should simplify and the answer would be 2/1. This is an improper fracture because numerator is bigger than the denominator so you ask yourself, “How many times can 1 multiply into 2.” The answer is a whole number which is 2

What is the value of x and y?

Answers

Answer:

[tex] x=\boxed{2} [/tex]

[tex] y=\boxed{4}[/tex]

Step-by-step explanation:

[tex] \begin{cases} y= 6x-8... (1)\\\\y=-3x+10...(2)\end{cases} [/tex]

From equations (1) & (2), we find:

6x - 8 = - 3x +10

[tex] \therefore 6x+3x = 8+10[/tex]

[tex] \therefore 9x = 18[/tex]

[tex] \therefore x =\frac{18}{9}[/tex]

[tex] \therefore x = 2[/tex]

Plug x = 2 in equation (1)

y = 6(2)-8 = 12-8 =4

So,

[tex] x=\boxed{2} [/tex]

[tex] y=\boxed{4}[/tex]

9. y = 8

10. n = 21

11. 44 = v

12. c = 35

Step-by-step explanation:

9. 9y = 72

Divide each side by 9

9y/9 = 72/9

y = 8

10. 3n = 63

Divide each side by 3

3n/3 = 63/3

n = 21

11. 4 = v/11

Multiply each side by 11

4*11 = v/11*11

44 = v

12. c/7 = 5

Multiply each side by 7

c/7*7 = 5*7

c = 35

y=8

A sentence (sometimes also called a formula) is simply a string of characters or symbols.

E.g., “sin2 x + cos2 x = 1” is a sentence as is “5 + 4”.

A statement is a sentence that is definitely either true or false.

What are the Euclidean postulates?

A straight line segment may be drawn from any given point to any other. A straight line may be extended to any finite length. A circle may be described with any given point as its center and any distance as its radius. All right angles are congruent.

What are the 5 postulates described by Euclid?

Euclid's postulates were: Postulate 1: A straight line may be drawn from any one point to any other point. Postulate 2:A terminated line can be produced indefinitely. Postulate 3: A circle can be drawn with any center and radius. Postulate 4: All right angles are equal to one another.

How many millimeters are equal to one kilometer?

Metric
1 kilometer = 1,000 meters
1 meter = 100 centimeters
1 meter = 1000 millimeters
1 centimeter = 10 millimeters

Answers

Answer: The answer would be 1,000,000, or one million.

Step-by-step explanation:

There are 1000 millimeters in a meter, and there is the same number of meters in one kilometer. So to solve for how many millimeters are in one kilometer, just multiply 1000 by 1000 to get 1,000,000. Hope this helps!

It will equal 1,000,000 kilometres

Question:
A running club keeps track of the number of hours each person has trained for a race and the length of time it takes the person to run the race. A scatter plot is graphed with the x-axis indicating the number of hours a runner has trained and the y-axis indicating the time, in minutes, it took to run the race. The equation y = 60 - 0.5x is used as the line of best fit of the data. What does the slope of the equation represent?

options:

a
Runners will decrease their race time by 2 minutes for every 1 hour they have trained.
b
Runners will increase their race time by 2 minutes for every 1 hour they have trained.
c
Runners will increase their race time by 1 minute for every 2 hours they have trained.
d

The solution is, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.

What is scatter plot?

A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are coded, one additional variable can be displayed.

Here, we have,

We are given the scatter plot which shows the distance he has run and the time it took for each run.

We are asked to determine a good prediction of how long it will take Tom to run the 6 mile race?

One way to predict the time is by drawing a line that best fits the given data.

As you can see, from the line of best fit, the time corresponding to the 6 miles is around 60 minutes.

Therefore, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.
