Order from greatest to least 2.007,2.714,2.09,2.97

1.  2.97

2.  2.714

3.  2.09

4.  2.007

Step-by-step explanation:

Line the numbers up underneath each other by lining up the decimals and add zeros to fill in spaces.  Then compare. Since the whole number (2) is the same in all of them then you compare the decimal side (7, 714, 90, and 970)

EX.  2.007

       2.714

       2.090

       2.970

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
