7p ( -3p +4) = -2 ( 2p - 1) + 10

so ima do one part first okay.

7p x -3p = -21p

7p x 4 = 28p

so now we put it as a equation. so you have now
-21p +28p = -2 (2p -1) +10

so ima do the second part.
-2 x 2p = -4p
2 x 1 = 2

so now you have -21p + 28p = -4p + 2 + 10

so im going to put all like terms together.

28p - 21p = 7p

7p = -4p + 2 + 10
<u>+4p  +4p</u>

11p = 2 + 10
 
<u> 11p = 12    </u>             
         11 

p = 12/11 *it's your answer

If h(x) = 5x - 3 and j(x) = -2x, solve hlj(2)] and select the correct answer below. (1 point)
BARSIC [14]

Answer:

-23

Step-by-step explanation:

We are given the functions;

h(x) = 5x - 3 and j(x) = -2x

Now, we want to find h[j(2)]

j(2) = -2(2)

j(2) = -4

Thus;

h(-4) = 5(-4) - 3

h(-4) = -20 - 3

h(-4) = - 23

4/9 / 9/5= the answer is
mr Goodwill [35]

Answer:

  20/81

Step-by-step explanation:

Without parentheses, it is hard to tell what you are dividing. We assume you want ...

  (4/9)/(9/5)

Then ...

\displaystyle\frac{\left(\frac{4}{9}\right)}{\left(\frac{9}{5}\right)}=\frac{4}{9}\cdot\frac{5}{9}=\frac{4\cdot 5}{9\cdot 9}=\frac{20}{81}

_____

As written (without parentheses), your expression is evaluated left to right, so evaluates to ...

  4/(9·9·5) = 4/405
