Where would parenthesis need to be placed in the expression to get a value of 44?
melisa1 [442]

Answer:

<em>one of the options are correct</em>

Step-by-step explanation:

Given the expression 2 + 32*5-3, we are to locate the point where parenthesis will be placed to get 44;

There is no point where we are we are going to put parenthesis to get 44

For Option A :

2+32×(5−3)

= 2+ 32 * 2

According to PEMDAS, multiplication is next in precedence

= 2(32*2)

= 2(64)

= 128

For Option B:

2+(32*5)-3

= 2+160-3

= 162-3

= 159

For Option C:

(2+32) * 5 - 3

= 34 * 5 -3

= 170-3

= 167

For Option D:

(2+3)2*5 - 3

5(2)*5 - 3

10*5 -3

= 50 - 3

= 47

<em>From the expansion, none gave us 44, hence none of the options are correct</em>
