Answer:

Step-by-step explanation:

It's like the same thing for adding. For example if you have 3 x 4. You can add 3 four times or you can add 4 three times. Like this.

3 + 3 + 3 + 3 = 12 because you know 3 + 3 =6 and 6 + 6 equals 12.

OR

4 + 4 + 4 = 12 because you know 4 + 4 = 8 and 8 + 4 equals 12.

Describe in your own words how to tell if an equation has infinite solutions or no solution at all

Answers

Answer:

We can identify which case it is by looking at our results. If we end up with the same term on both sides of the equal sign, such as 4 = 4 or 4x = 4x, then we have infinite solutions. If we end up with different numbers on either side of the equal sign, as in 4 = 5, then we have no solutions.Step-by-step explanation:

What is the probability of rolling either two identical numbers or rolling a sum of 8 using two number cubes, each labeled 1 – 6?

Answers

Answer:

5/18

Step-by-step explanation:

We have 2 things to consider here, rolling two identical numbers, or rolling a sum of 8

Rolling two identical numbers

To make this simple, think about how many possibilities there are to have two identical numbers. (1,1) (2,2) (3,3) (4,4) (5,5) (6,6). The total amount of possibilities for rolling two dice is 6*6 which is 36. That would be 6/36 which is 1/6

Rolling a sum of 8

The numbers which add up to 8 are, (2,6)(3,5)(4,4)(5,3)(6,2). With 36 total possibilities, it would be 5/36.

However, we can see, (4,4) is repeated, so we have to subtract 1/36.

Answer

1/6 + 5/36 - 1/36

6/36 + 5/36 - 1/36

10/36

5/18

Answer:

5/18

Write the equation of the line in slope-intercept form.

The equation of the line in slope-intercept form is

Answers

Answer:

y = 50x + 20

Step-by-step explanation:

[tex]m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

Use the slope-intercept formula to find the slope.

[tex]m = \frac{120 - 20}{2 - 0}[/tex]

[tex]m = \frac{100}{2} = 50[/tex]

The y-intercept is where the line crosses the y-axis.

Answer:

y = 50x + 20

Step-by-step explanation:

finding slope or gradient, choose any two points on the line i.e (2.0, 120) and (0.0, 20)

m = (y2 - y1)/(x2 -x1)

= (120-20)/(2.0-0.0)

= 100/2

= 50

finding the equation of the line using point (0,20)

=> y = mx + c

=> 20 = 50*0 + c

=> c = 20

so equation of the line

=> y = 50x + 20

at 9 am you have to run 2 miles. at 9:24 am you have run 5 miles. what is your running rate in minutes per mile

Answers

The answer is 5 minutes
You ran three miles in 24 minutes so your rates is 3/24 miles per minute
To convert to miles per hour you would multiple by 60minutes/1hr
So 3/24 x 60/1 which simplifies to
15/2 miles per hour

The distance on Map A from Millersville to Augusta is in. The map scale is . Find the distance on Map B if the scale is . Round to the nearest tenth.

Answers

Answer: 4.1 inches is the distance on map B

Step-by-step explanation: Map A scale: 1 inch represents 75 mies

Multiply the given inches by the scale  miles per inch distance from map A.

6.5 inches × 75 mi/inch represents 487.5 miles

Take that distance and divide by the scale miles per inch from map B

487.5miles/120 = 4.0625 inches

Rounded to nearest tenth, that is 4.1 inches.

The distance on Map B if the scale is 1 in = 120 miles is 780 miles.

What is scale factor?

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Given that, the distance on Map A from Millersville to Augusta is 6.5 in. The map scale is 1 in = 75 miles.

Number of miles in 6.5 inches =6.5×75

= 487.5 miles

The distance on Map B if the scale is 1 in = 120 miles

Number of miles in 6.5 inches =6.5×120

= 780 miles

Therefore, the distance on Map B if the scale is 1 in = 120 miles is 780 miles.

Is it a reflection?

Answers

Answer:

x = 30 degrees

Step-by-step explanation:

When two parallel lines are intersected by a transversal, the alternate corresponding angles are supplementary, meaning their degree measures add up to 180. One can apply this here by stating that the two given angles add up to 180. Then one can simplify and use inverse operations to solve for (x).

(6x - 5) + (x - 25) = 180

6x - 5 + x - 25 = 180

7x - 30 = 180

    +30    +30

7x = 210

/7      /7

x = 30
