Step-by-step explanation:
The most basic and common reason to use parentheses, brackets, and braces is to control the order of operations.
<h3>What are parentheses?</h3>
In mathematics, parenthesis is used to arrange numbers in the sequence of operations, clarify numbers, and denote multiplication.
Suppose you have an expression as:-
E = { ( 5-2 )8} 6
In this case, you would calculate 5 minus 2 first (parentheses), then multiply by 8 (brackets), then complete the part inside the curly braces, and finally multiply by 6.
Therefore the most basic and common reason to use parentheses, brackets, and braces is to control the order of operations.

Step-by-step explanation:
tan 60 = 21 ÷ y
1.73 = 21 ÷ y
y = 21 ÷ 1.73
y = 12.14
tan 30 = x÷ 12
0.6 x 12 = x
x = 7.2
Answer: The missing coordinate -10
Step-by-step explanation: (4,r) = -10
50k is the same as 50,000
73% = 73/100 = 0.73
Multiply 50,000 with 0.73
50,000 x 0.73 = 36500
You spend $36500.
Subtract 36500 from the total
50,000 - 36,500 = $13,500
$13,500 is the amount of money you have left.
