Perform the indicated operation
17-19 ÷ (5)(5) -30
Show parentheses
what do u mean
this is what i come up with:
-2 ÷ -5 = .4
It could also be
(-2/25) -30 = - 32 2/5
or
17 - (19/25) -30 = -13 19/25
or a lot of other answers.
What you calculated was
(17-19)÷ [(5)(5) -30]= -0.4
If you don't understand the importance of when and how to use parentheses, you are going to have a lot of difficulty with algebra
the way the problem was originally written is the way it is presented to me.
The only parentheses are the ones in the denominator around the 5's
To perform the indicated operation, we need to follow the order of operations (also known as PEMDAS), which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Let's break down the problem step by step:
1. First, let's start with the multiplication. We have (5)(5), which equals 25.
2. Next, let's perform the division. We have 19 ÷ 25. Dividing 19 by 25 gives us a decimal value of approximately 0.76.
3. Now, let's subtract. We have 17 - 0.76. Subtracting 0.76 from 17 gives us a value of approximately 16.24.
4. Finally, let's perform the last subtraction. We have 16.24 - 30. Subtracting 30 from 16.24 gives us a value of approximately -13.76.
Therefore, the answer to the expression 17 - 19 ÷ (5)(5) - 30 is approximately -13.76.
