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.

The question is asking you to add mixed numbers together. The two mixed numbers you want to add up are 2 1/3 and 3 1/3.
This question is fairly simpler than other mixed number or fraction types of problems because the fractions attached to the whole numbers already come having common denominators.
This means you don't have to do anything extra to the fractions to add them; you can just add the numerators (top numbers) together and keep the denominators the same.
Add the fractions (1/3) together first.
1/3 + 1/3 = 2/3
Now add the whole numbers together.
2 + 3 = 5
Combine the whole number and the fraction together to create the mixed number as your answer. Your answer is 5 and 2/3.
