Answer:
x > -7
Step-by-step explanation:
Isolate the variable, x. Treat the < sign like an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction
First, subtract 15 from both sides:
-8x + 15 (-15) < 71 (-15)
-8x < 71 - 15
-8x < 56
Next, divide -8 from both sides of the equation. Note that when you divide by a negative number, you must flip the sign:
(-8x)/-8 < (56)/-8
x < (56)/-8
x > -7
x > -7 is your answer.

Answer:
2 / 6 = 0.3333...
4 / 6 = 0.6666...
5 / 6 = 0.83333...
Step-by-step explanation:
Let us assume the first even number = n
The second consecutive even number = n + 2
The third consecutive even number = n + 4
The addition of the three consecutive even numbers is 42 and it is already given in the question. Based on the information's given in the question, the answer can be easily deduced.
Then, the equation can be written as
n + (n + 2) + (n + 4) = 42
3n + 6 = 42
3n = 42 - 6
3n = 36
n = 36/3
= 12
So
The first even number = 12
The second consecutive even number = n + 2
= 12 + 2
= 14
The third consecutive even number = n + 4
= 12 + 4
= 16
So the three consecutive even numbers are 12, 14, 16.
