6 x(5+7)/4 - 7 X 3x3
which of the folling is the number of centimeters in 4 meters? 0.04, 0.4,40,400
good answer!
To solve this math expression: 6 x (5 + 7) / 4 - 7 x 3 x 3, we can follow the order of operations, also known as PEMDAS:
1. Parentheses: Simplify what's inside parentheses first.
2. Exponents: Solve any exponentiation.
3. Multiplication and Division: Perform multiplication and division from left to right.
4. Addition and Subtraction: Finally, perform addition and subtraction from left to right.
Let's break down the expression step by step:
Step 1: Simplify the expression inside the parentheses.
6 x (5 + 7) / 4 - 7 x 3 x 3
= 6 x 12 / 4 - 7 x 3 x 3
= 6 x 12 / 4 - 7 x 9
Step 2: Perform the multiplication and division from left to right.
= 72 / 4 - 7 x 9
= 18 - 7 x 9
Step 3: Perform the remaining multiplication.
= 18 - 63
Step 4: Perform the subtraction.
= -45
So, 6 x (5 + 7) / 4 - 7 x 3 x 3 is equal to -45.
