Answer:
a = <u>2 - 3b</u>
2
Step-by-step explanation:
3(a + b) = a + 2 expand
3a + 3b = a + 2
3a - a = 2 - 3b
2a = 2 - 3b
a = <u>2 - 3b</u>
2
That would be B
|-6| + |4| = 6 + 4 = 10
C) 120
Because if you multiply 40x3=120
The key word to know to multiply Is per.
Let the first number be x
1st number = x
2nd number = x + 2
3rd number = x + 4
4th number = x + 6
5th number = x + 8
x + x + 2 + x + 4 + x + 6 + x + 8 = 120
5x + 20 = 120
5x = 100
x = 20
3rd number = x + 4 = 20 + 4 = 24
Answer: 24
