Answer:
a, 6
Step-by-step explanation:
7x + 2y = 48
7x + 2(3) = 48
7x + 6 = 48
7x = 48 - 6
7x = 42
x = 42 / 7
x = 6
Answer:
all real numbers
Step-by-step explanation:
That is 2015! or 2015 factorial

Answer:
Concept: Number Analaysis
- The first option goes back 9 spaces hence

- Second one you to forward 10 spaces hence

- Using that logic solve the rest!
-6 + x = -3
x = -3 + 6
x = 3 <==
-x = 3 - 4x + 6
-x + 4x = 3 + 6
3x = 9
x = 9/3
x = 3 <==
