On a typical number line, we have basically two directions that we can move on. Either to the left where the numbers are negative, of to the right where the numbers are positive.
Given that point E has a coordinate of 1 on a number line, and we are told that the distance between E and another point on the number line is 11 (EG), the possible coordinates of point G are two (either we are moving to the right or to the left). Therefore, possible coordinates of G are:
1 - 11 = -10 (to the left)
1 + 11 = 12 (to the right

Help and explain <br><br> Don’t use for points or I will take it back
KIM [24]

Step-by-step explanation:

step 1. x + 51 + 39 + 127 = 360 (1 revolution is 360°)

step 2. x + 90 + 127 = 360

step 3. x + 127 = 270. (subtract 90 on both sides)

step 4. x = 143° (subtract 127 on both sides)

The value of 9−y is twice the value of y. What is the value of y?
ElenaW [278]

Answer:

y = 3

Step-by-step explanation:

9 - y = 2y

<u>Step 1:  Add y to both sides</u>

9 - y + y = 2y + y

9 = 3y

<u>Step 2:  Divide both sides by 3</u>

9 / 3 = 3y / 3

3 = y

Answer:  y = 3
