Melissa is measuring 132 oz of rice into 1 pound containers. how many 1 pound containers will she need to hold all of the rice? how many ounces of rice will she need to buy if she needs 10 lb of rice? show your work

Step-by-step explanation:

Let's work in pounds everywhere.  Convert 132 oz of rice into lb:

132 oz          1 lb

 ·    =  8.25 lb

     1            16 oz

Melissa will be able to fill 8 1-lb containers with rice, but will have 0.25 lb left over.

If she wants 10 lb of rice and is curious regarding how many oz that would be, take this 10 lb and multiply it by the conversion factor shown above:

10 lb        16 oz

 ·    =  160 oz

   1           1 lb

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
