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.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
