What is the value of n
9*27+2*31-28=n
What is 9×27+2×31-28=n
9×27+2×31-28=n
Do the multiplication first.
Then do the addition and subtraction.
I'll be glad to check your answer.
27×9=243+31×2=62=243+62=305_28=277
To find the value of n in the equation 9*27+2*31-28=n, we can follow the principles of the order of operations (also known as PEMDAS). PEMDAS stands for Parentheses, Exponents, Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).
1. First, let's start with the multiplication: 9*27 and 2*31.
9 * 27 = 243
2 * 31 = 62
Now, we have the equation: 243 + 62 - 28 = n.
2. Next, let's handle the addition and subtraction in the order they appear from left to right:
243 + 62 = 305
305 - 28 = 277
Therefore, the value of n in the equation 9*27+2*31-28=n is 277.
