Answer:
<h3>
AB = 2</h3>
Step-by-step explanation:
If B is the midpoint of AC then:
AB = BC
4x - 10 = x - 1
+10 +10
4x = x + 9
-x -x
3x = 9
÷3 ÷3
x = 3
AB = 4x - 10 = 4×3 - 10 = 12 - 10 = 2
Point D will pass from (1,-2) to (-1,2)
The second choice is the correct one.
Answer:
Total number of seats on plane = 150 seats
Step-by-step explanation:
Number of seats on right = 3 seats in each row
Number of seats on left = 2 seats in each row
Total number of seats on right = 90
So, we can find number of rows as:
Number of rows = Total number of seats on right / Number of seats on right in each row
Number of rows = 90/3 = 30 rows
Total number of seats on left = Total number of rows × Number of seats on left in each row
Total number of seats on left = 30 × 2 = 60 seats
Total number of seats on plane = total seats on right + total seats on left
Total number of seats on plane = 90 + 60 = 150 seats
