3x5+10x3/ 20-(5+6)
my work
45/9=5
yes or no please help
3x5+10x3/ 20-(5+6)
= 15 + 30/20 - 11
= 15 + 3/2 - 11
= 5 1/2 or 11/2 or 5.5
what you did is 3x5+10x3/ (20-(5+6))

To solve this expression, follow the order of operations (PEMDAS - Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).
Given expression: 3x5 + 10x3 / 20 - (5+6)
First, simplify the expression inside the parentheses:
3x5 + 10x3 / 20 - 11
Now, perform the multiplication and division from left to right:
15 + 30 / 20 - 11
Since division is performed before addition and subtraction, divide 30 by 20:
15 + 1.5 - 11
Now, perform the remaining addition and subtraction from left to right:
16.5 - 11
Finally, subtract 11 from 16.5:
5.5
Therefore, the result of the expression is 5.5.
To verify your work, let's perform the same steps:
3x5 = 15
10x3 / 20 = 1.5
5 + 6 = 11
Now substitute the values back into the expression:
15 + 1.5 / 20 - (5+6)
15 + 1.5 / 20 - 11
15 + 0.075 - 11
15.075 - 11 = 5.075
It seems there was a mistake in your calculation. The correct result is approximately 5.075, not 5. Therefore, the answer to the question "45/9=5" is no.
