absolute value problems
|30|/|10| + |-2+7|/5 x 8 = 17.4
is this answer correct?
no,
|30|/|10| + |-2+7|/5 x 8
= 3 + 5/5*8
= 3 + 1*8
= 3+8
= 11
How did you get 17.4 ???
3+9/5x8 =
3+1.8(9/5 = 1.8)x8=
3=14.4
To determine if the given expression is correct, we need to simplify it step by step.
First, let's simplify the absolute value expressions inside the expression:
|30| = 30
|10| = 10
|-2 + 7| = |5| = 5
Now, let's plug in these values back into the original expression:
|30|/|10| + |-2+7|/5 x 8 = 30/10 + 5/5 x 8
Next, let's simplify the remaining expression:
30/10 = 3
5/5 = 1
Plugging these values back into the original expression:
3 + 1 x 8 = 3 + 8 = 11
Therefore, the correct answer to the expression is 11, not 17.4.
To check our work, you can use a calculator or perform the mathematical calculations manually according to the order of operations (PEMDAS).
