Answer:
C
Step-by-step explanation:
I'm not going to do the entire question, but I'll do the first part.
For the first part, you have to set up an inequality. Use context clues, such as
no more than (the one used in this sentence) to figure out what the symbol should be for the inequality.
In this case, because it is NO MORE THAN 6400, it would be:
6400

250r + 475p
where r represents the # refrigerators, and p represents the # pianos
Now that you have the equation, make the graph, then for the 3rd part, plug in 12 and 8 to r and p to see if it keeps the inequality true.
Hope this helps! :)

Answer:
Marcelle will use 4 plates of the 25 lb & 2 plates of the 5 lb to fabricate the 110 lb weight lifting bar.
Step-by-step explanation:
There are 6 plates which consist of 25 lb plates and 5 lb plates.
We need to figure out how many of each one compose 110 lb.
Thus, 25 x 4 = 100... 4 plates of 25 pounds.
5 x 2 = 10 ... 2 plates of 5 lbs.
100+10= 110, which is our goal! And a total of 6 plates were used!
All things put into great consideration, Marcelle will use 4 plates of the 25 lb & 2 plates of the 5 lb to fabricate the 110 lb weight lifting bar.
I hope this helped!
