Answer:
4th option because the two negatives will become positive and the 3rd will make it negative again
Answer is a= 51/7 or 7 2/7
Step by step
-2/3 (a + 3) = 5/3a - 19
Distribute to resolve parentheses
-2/3a -2 = 5/3a - 19
Now to move variables to one side
Add 2/3a to both sides
-2/3a + 2/3a -2 = 5/3a + 2/3a -19
Combine like terms
-2 = 7/3a -19
Add 19 to both sides to isolate variable
-2 +19 = 7/3a -19 + 19
17 = 7/3a
Divide both sides by 7/3 to solve for a
(Remember when you divide a fraction, flip it and multiply.)
17 * 3/7 = a
51/7 = a

Answer:
V
Step-by-step explanation:
This series is a letter, followed by a number where the letter is the previous letter in the alphabet and the number is increasing by 3
Well to find out X, you have to do the opposite to what it's asking to each side. So 11=x-4
+4 onto the 11 and + 4 on to the -4 which means you just have 15=X
Answer:
- 9z^2
Step-by-step explanation:
Since the negative sign is outside of the parentheses it is not raised to the power of 2
- ( 3z) ^2
- ( 3z) * (3z)
- 9z^2
