What are you to do with this equation?

Use the distributive law:

3(7m - 6n)  =  3(7m) - 3(6n)  =                                <--- finish this

2(6m - 9n)  =  2(6m) - 2(9n)  =                               <--- finish this

3(7m - 4n)  =  3(7m) - 3(4n)  =                                <--- finish this

12(2m - n)  =  12(2m) - 12(n)  =                               <--- finish this

Can you finish these?

For the first question, start at the top and use the Distributive Law until you find one that works:

3(7m - 6n)  =  3(7) - 3(6m)  =                            <--- finish this

2(6m - 9n)  =  2(6m) - 2(9m)  =                         <--- finish this

(etc.)

Second question:  (5c - 2c)(d + 4)

   first:  simplify 5c - 2c = 3c --->  3c(d + 4)

   then, use the Distributive Law:  3c(d) + 3c(4)  =                 <--- finish this

Third question:  6s + 4t - 5(s + t)

                   =  6s + 4t - 5(s) - 5(t)

                   =  6s + 4t - 5s - 5t                             <--- finish this

The volume of a box can be found using the formula:  Volume = length x width x height

          3000  =  20 x 5 x height

          3000  =  100 x height

          30 cm = height

To change mm to inches, multiply by 0.03 93 70 1

To change this answer into feet and inches, divide by 12; the quotient is the number of feet, the remainder is the number of inches. 

Using the distributive law on  5(3x + 1 + 2)

she would get:                      5(3x) + 5(1) + 5(2)

Use the distributive law on each of these:

16(x + y)  =  16(x) + 16(y)  =                                <--- can you make this look a little simpler?

4(x + 3y)  =  4(x) + 4(3y)  =                                  <--- can you make this look a little simpler?

2(2x + 6y)  =  2(2x) + 2(6y)  =                               <--- can you make this look a little simpler?

(2x + 6y) + (2x + 6y)  

   =  2x + 6y + 2x + 6y

         =  2x + 2x + 6y + 6y  =                                <--- can you make this look a little simpler?

Can you now pick out your answer?

                                                                            -0.3 - (1 - 7x)  =  -5 + 3.7x

Distribute the minus sign in front of the parentheses:  -0.3 - 1 + 7x  =  -5 + 3.7x

Combine the numbers on the left side:                             -1.3 + 7x  =  -5 + 3.7x

Subtract 3.7x from both sides:                                      -1.3 + 3.3x  =  -5

Add 1.3 to both sides:                                                            3.3x  =  -3.7

Divide both sides by 3.3:                                                            x  =  -3.7/3.3

Use a calculator to finish this:

7x + 5 - 2x   =  -50

Simplifying the left side:    5x + 5  =  -50

Subtracting 5 from both sides:  5x  =  -55

Dividing both sides by 5:            x  =  -11

Q2 is the median of the data: Q2 = -0.5

Q1 is the median of the data below Q2:  Q1 = -5

Q3 is the median of the data above Q2:  Q3 = 6

Quadrant I has points in which both the x-value and the y-value are positive.
