The way I do this is I start at 7, and count up to 12. 7, 8, 9, 10, 11, 12. And then I count how many numbers are there between 7 and 12. And there is 5. This is how I did subtraction in Elementary school.

12 - 7 is 5. you can count down 7 times from 12 like: 12, 11, 10, 9, 8, 7, 6, 5.

We can’t understand how to find the pattern
cupoosta [38]

Answer:

Pattern: subtract 2 from the input to get the output

When the input is 9, the output is 7

When the input is 13, the output is 11

Step-by-step explanation:

» <u>Application + Solution</u>

To find the pattern, we have to look for common things we notice between the input and output.

  • After analyzing, we can surely notice that we subtract two from the input each time to get the output because 3 - 2 = 1, 8 - 2 = 6, 15 - 2 = 13, and 20 - 2 = 18.

Now that we realized the pattern, we subtract 2 from 9 and 13.

  • 9 - 2 = 7
  • 13 - 2 = 11

PLEASE HELP<br><br><br> What is the value of x?
AleksAgata [21]
The angles inside a triangle add up to 180°
The 3rd angle is supplementary to (6x+1)°
Supplementary means they make a straight line (i.e 180°)

1st angle = 79°
2nd angle = (2x+10)°
3rd angle = 180° - (6x+1)°

180 = 79 + (2x+10) + 180 - (6x+1)
180 = 79 + 2x + 10 + 180 - 6x - 1
combine like terms
180 - 180 - 79 - 10 + 1 = 2x - 6x
-88 = -4x
-88/-4 = x
22 = x

Me need help pweaseee can anyone help
Kryger [21]

Answer:

B

Step-by-step explanation:

A 90 degree rotation would be a rotation of 90° about the origin. Knowing this, we can eliminate C since it is a 180° rotation. We can also eliminate A, as it would be a 0° or 360° rotation. This leaves us with B and C.

A counterclockwise rotation would be one that goes the opposite direction of the rotation of the hands of a clock. A 90° counterclockwise rotation would yield triangle B, making that our answer.

I hope you find my answer and explanation to be helpful. Happy studying.
