Answer:

1. distributive

2. 2(x + x)

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

Answer:

3x+12

Step-by-step explanation:

This is distributive property

So you multiply by 3 with the numbers inside the parenthesis

3 times x is 3x

3 times 4 is 12

So the answer is

3x+12

Answer:

3x+12

Step-by-step explanation:

Distribute(multiply) the 3 to the numbers in the parenthesis and the variable.  

angle x= 120

if you draw a straight line passing through x and parallel to the 2 straight lines that are up and down you will get the Z symbol then the angle will be the sum of the other 2 angles

Answer:

x = 120 degrees

Step-by-step explanation:

you would do 70+50 = 120

360 - 120 = 240

240 / 2 = 120

I got the 360 degrees because I thought of the it as a circle instead of triangles.

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:

Answer:

Since radical 45 is equal to radical 9 times radical 5, and because radical 9 is equal to 3 (since 9 is a perfect square), we can simplify radical 45 to 3 times radical 5

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

Step-by-step explanation:

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.

I hope this helped. I am sorry if I didn't do much of help. Have a wonderful day.

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.

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.

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
