How do I solve p(q-2)(r-3)

Since you have parentheses, you will first multiply (q-2)*(r-3) which equals (qr+6). So now its simplified to p(qr+6) which equals pqr+p6.

Brooke saved the same amount of money each week for four weeks. She made this table to show how much money she saved.
Musya8 [376]

Answer:

In 10 weeks of time, Brooke would  earn $ 20.

Step-by-step explanation:

Here, according to the table:

The money saved in week 1   =  $ 2   =   $(1  x 2)

The money saved in week 2  =  $ 4   =  $ ( 2 x 2)

The money saved in week 3   =  $ 6  =  $ ( 3 x 2)

The money saved in week 4   =  $ 8 =   $ ( 4 x 2)

So, by the graph relation, we can see that:

The amount saved in n weeks = ( n x 2) dollars

So, the amount saved by Brooke in 10 weeks is:

Put n =  10, we get:

The money saved  = 2 n = 2 x 10 = $ 20

Hence, in 10 weeks of time, Brooke would  earn $ 20.

Can anyone help me I was self isolating when my class was taught this and I can't get in contact with my teacher
Aleonysh [2.5K]

Answer:

Step-by-step explanation:

3x +2y = 13   -----------------(i)

x + 2y = 7    ----------------(ii)

Multiply the equation (ii) by (-1) and then add.

(i)              3x + 2y = 13

(ii)*(-1)      <u>-x    - 2y = -7 </u>        {Now, add and y will be eliminated}

                 2x       = 6

                        x = 6/2

x = 3

Plug in x = 3 in equation (i)

3*3 + 2y = 13

  9 + 2y = 13

         2y= 13 - 9

         2y = 4

           y = 4/2

y = 2
