A bag of 8 baseballs and 2 basketballs weighed 80 ounces. A bag of 5 baseballs and 3 basketballs weighed 85 ounces. How much does each type of ball weigh? HELP ASAP

Step-by-step explanation:

Let "e" represent the weight of a baseball, and "k" represent the weight of a basketball, all weights being in ounces. Then the given information can be summarized as ...

  8e +2k = 80

  5e +3k = 85

We can divide the first equation by 2 and subtract 4e to get ...

  k = 40 -4e

This can be substituted into the second equation to give ...

  5e +3(40 -4e) = 85

  -7e +120 = 85 . . . . . . . simplify

  35 = 7e . . . . . . . . . . . . add 7e-85

  5 = e . . . . . . . . . . . . . . divide by 7

  k = 40 -4·5 = 20 . . . . . find k using the above equation

The weight of a baseball is 5 ounces; a basketball, 20 ounces.

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
