Hello!
Since D is the midpoint and the two equations are and both sides of point D the equations equal each other
9x - 7 = 3x + 17
Now you solve it algebraically
Add 7 to both sides
9x = 3x + 24
Subtract 3x from both sides
6x = 24
Divide both sides by 6
x = 4
Now we put this into both equations and add them
9(4) - 7 = 29
3(4) + 17 = 29
29 + 29 = 58
The answer is 58 units
Hope this helps!
Answer:
b. 25%
Step-by-step explanation:
(new - old)/ old * 100%
150 - 120 = 30 ... 30/120 = .25 * 100% = 25%
Answer:
m>16
Step-by-step explanation:
Multiply both sides by 2.
Use an open circle to mark 16, and draw an arrow facing right (greater than)
-6 < x + 1 ≤ 1
<u>-1 -1 -1</u>
-7 < x ≤ 0
-7 < x or x ≤ 0
x > -7 or x ≤ 0
