15 (negative 42 x + 40) = 15 (negative 8 x + 244)

  x = -6

Step-by-step explanation:

Maybe you want to solve for x:

  15(-42x +40) = 15(-8x +244)

Divide by 15:

  -42x +40 = -8x +244

Add 42x-244

  -204 = 34x

Divide by 34

  -6 = x

The solution is x = -6.

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00
