Answer:uidelines called the order of operations, which outlines the order in which parts of an expression must be simplified.
ORDER OF OPERATIONS
When simplifying mathematical expressions perform the operations in the following order:
1. Parentheses and other Grouping Symbols
Simplify all expressions inside the parentheses or other grouping symbols, working on the innermost parentheses first.
2. Exponents
Simplify all expressions with exponents.
3. Multiplication and Division
Perform all multiplication and division in order from left to right. These operations have equal priority.
4. Addition and Subtraction
Perform all addition and subtraction in order from left to right. These operations have equal priority
Step-by-step explanation:
<span>f x=0 ==>x^4+400=0+400=400</span>
Solution
Step 1
The opposite angles of a parallelogram are equal:
Step 2

The equation is made true by the opposite angles theorem is
85 + y = 3y - 15
or
y = 50
The Original Price is $40
Explanation:
50 1 20
—- = — Which means ——
100 2 40
Answer:
d=1/2
b=1/25
b(row 2)=1/5
e=7/100
explanation: think about them as numbers out of 100 then simplify :)
