Answer:
A. Infinitely many
Step-by-step explanation:
9x + 27 = 9(x + 2) + 9
Distribute on the right side.
9x + 27 = 9x + 18 + 9
Combine like terms on the right side.
9x + 27 = 9x + 27
Subtract 27 from both sides.
9x = 9x
Divide both sides by 9.
x = x
x = x is a true statement for every value of x. Therefore, any value you substitute in for x will make the original equation true. That means there is a infinite number of solutions.

5/8 = 0.625
3/4 = 0.75
1/2 = 0.5
9/16 = 0.5625
Least to Greatest
1/2, 9/16, 5/8, 3/4
Answer:
parentheses come first
Step-by-step explanation:
Parentheses are symbols that group things together. This becomes very important in numerical expressions, because operations inside parentheses are always completed first when evaluating the expression. Let's review the order of operations. You can see that, according to the order of operations, parentheses come first.
