What is the first step you should take to solve the following expression? end of exam (2 ÷ 12) - 3 2 + 4 × 8 - 3 3 a. 4 × 8 b. 32 c. 2 ÷ 12 d. –3 3

The correct option is : C. 2 ÷ 12

Step-by-step explanation:

The correct order of operations to solve a given expression is explained by BODMAS.

BODMAS stands for Bracket, Of, Division, Multiplication, Addition and Subtraction.

Therefore, the first step in solving the given equation is to solve the expression inside the brackets by division, followed by multiplication, addition and lastly subtraction.

(2 ÷ 12) - 32 + 4 × 8 - 33                                        (bracket of division)

= 0.1666 -  32 + (4 × 8) - 33                                   (multiplication)

= 0.1666 - 32 + 32 - 33  

= (0.1666 + 32) - 32 - 33                                        (addition)

= (32.1666 -  32) - 33                                              (subtraction)

= (0.1666  - 33 )

= -32.8334

Therefore, the first step in solving the given equation is to solve the expression inside the brackets by division.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
