) If * stands for /, /stands for -, +stands for * and –stands for +, then 17/5*4+19-8?
A)1.25
B) 24.5
C) 12.8
D) 22.4
Ahhh, now your definition is different from the last time.....
17/5*4+19-8 becomes
17-5/4*19+8
= 17-1.25*19+8
= 17 - 23.75 + 8
= 1.25
To solve the equation using the given replacements:
17/5 * 4 + 19 - 8
We can substitute the symbols with their corresponding replacements:
17-5/4*19+8
Now let's simplify the expression step by step:
17 - 5/4 * 19 + 8
17 - 1.25 * 19 + 8 (since / stands for - and * stands for /)
17 - 23.75 + 8 (calculating the multiplication)
-6.75 + 8 (subtracting)
1.25 (adding)
So, 17/5*4+19-8 is equal to 1.25.
The correct answer is A) 1.25.
To solve the given expression, we need to substitute the symbols according to the given instructions:
"*" stands for "/", "/" stands for "-", "+" stands for "*", and "-" stands for "+".
Let's replace the symbols in the expression:
17/5 * 4 + 19 - 8
Using the given instructions:
17/5 * 4 = 17-5 / 4
= 12/4
= 3
Now reordering the expression:
3 + 19 - 8
Evaluating from left to right:
3 + 19 = 22
22 - 8 = 14
Therefore, the value of the expression is 14.
None of the given answer choices match the result, so the correct answer cannot be determined based on the given information.
