PLS HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Which statement is true?A. 25-15×4-3×2=30B. 24-15×(4-3)×2=30C. (24-15)×4-3×2=30D. (24-15)×4-3×2=66

Answer 1

The correct statement is C.

To notice this, we need to remember the correct order of operations:

• Parentheses

,

• Powers and roots

,

• Multiplications and divisions

,

• Additions and subtractions.

Using this ordering we have for each operation:

A.

`\begin{gathered} 25-15*4-3*2=25-60-6 \\ =-41 \end{gathered}`

B.

`\begin{gathered} 24-15*(4-3)*2=24-15*1*2 \\ =24-30 \\ =-6 \end{gathered}`

C.

`\begin{gathered} (24-15)*4-3*2=9*4-3*2 \\ =36-6 \\ =30 \end{gathered}`

D.

`\begin{gathered} (24-15)*4-3*2=9*4-3*2 \\ =36-6 \\ =30 \end{gathered}`

Hence the only correct result in the operations is the one given in option C.
