Answer: Hope this helps.

13, 7

Step-by-step explanation:

Number one is 13

Number two is 7

Well 7 x 2 = 14, 14-1 = 7, and 7+13 = 20 making the answers true.

I figured out this number by eliminating numbers, I started with 5, ended with 8 to make a range of the possible numbers. Since 5 was too low and 8 was too high I knew the number had to be either 6 or 7, so I did 7 and I got the answer.

Answer:

7 and 13

You can set up a simple equation to solve this: <u>x + (2x-1) = 20</u>

The x stands for the second, smaller number because the larger number is one less than twice it. When added together, they equal 20.

Now, you just solve for x. It goes as follows:

x + 2x - 1 = 20

3x - 1 = 20

3x = 21

<u>x = 7</u>


Since one number is 7, the other number has to be 13 to add up to 20.


Hope this helps!!! :)

Please help on question 12 or 13 as soon as possible
Anna007 [38]

Answer:

to know the summation of angles: (n-2)*180

here (n) represent numbers of sides

12)we have 5 sides (n=5)

(5-2)*180=540

x=540-(105+135+92+87)=121

13)we have 8 sides (n=8)

(8-2)*180=1080

x=1080-(116+158+141+124+136+132+129)=144

I hope it will help

Find the slope of (1,8) and (-1,-4)
aniked [119]

Answer: slope= 6

Slope intercept equation= y= 6x +2

Step-by-step explanation:

Slope formula: (y2 - y1) ÷ (x2 - x1) > (-4-8) ÷ (-1-1) = -12/-2 or 6

Plug slope (-6) and one coordinate into point slope form: y-1=m (x-1)

where m is slope and (1,8) would be (x,y)

Y-8= 6(x-1) > y-8 = 5x -6 > y= 6x +2
