Mathematics
1 answer:
Sidana [21]3 years ago
5 0

Answer:

b > 3

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

<u>Algebra I</u>

  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define</u>

3b + 12 > 27 - 2b

<u>Step 2: Solve for </u><em><u>b</u></em>

  1. Add 2b on both sides:                    5b + 12 > 27
  2. Subtract 12 on both sides:              5b > 15
  3. Divide 5 on both sides:                   b > 3

Here we see that any value <em>b</em> greater than 3 would work as a solution to the inequality.

1/8

Step-by-step explanation:

To find the common difference, subtract the first term (1/4) from the second term (3/8); it's 1/8.  Notice that if you subtract 3/8 from 1/2 as a check, you obtain 1/8 again.

Please solve and show your work: (-4m^9+2m^7-14m^6)÷2m^3
katrin2010 [14]
The first step for solving this expression is to write the division as a fraction. 
\frac{-4m^{9}+2 m^{7} -14 m^{6}   }{2} × m³
Factor out 2 from the numerator (top) of the fraction.
\frac{2(-2 m^{9} + m^{7}-7 m^{6} )  }{2} × m³
Reduce the fraction with 2.
(-2m^{9} + m^{7} - 7m^{6})m³
Lastly,, distribute m³ through the parenthesis to get your final answer.
-2m^{12} + m^{10} - 7m^{9}
Let me know if you have any further questions.
