Alright so think of it this way. You want the number of hamburger patties to equal the number of rolls with as little packages as possible.
              # of Packages         # per package        total #
Patties               1            x               6              =     6    
Rolls                  1            x               8              =     8

As you see above, the total number of patties and rolls is related to the product of the number of packages and the number per package.
Therefore to answer this problem, just find the least common multiple of 6 and 8:

Multiples of 6: 6, 12, 18, 24, 36...
Multiples of 8: 8, 16, 24, 32, 40....

24 is the least common multiple. To get to 24, you multiply 6 by 4 and 8 by 3. Therefore, you need 4 packages of 6 hamburgers, and 3 packages of 8 rolls.

This is confirmed in the table below:
               # of Packages         # per package        total #
Patties               4            x               6              =     24   
Rolls                  3            x               8              =     24

Find the value of c that makes each trinomial a perfect square. Then write the trinomial as a perfect square.
musickatia [10]

Answer:

d. c = 100; (x – 10)²

Step-by-step explanation:

Note that (x+a)²=x²+2ax+a².

In our case, 2a=-20, so 'a' must be -10.

Since c=a², and a=-10, c=(-10²)=100.

Since a=-10, the perfect square is (x – 10)²

A store has a 25% off sale on coats. Marcy saved $18.75 on the coat she bought. What was the original price of the coat?
Tcecarenko [31]

Answer:

$25

Step-by-step explanation:

18.75 is 75% of a value. You can easily find the answer by dividing 18.75 and 0.75.

When you have a problem like x*5=30, you divide 30/5 to get 6. Same here, x*0.75=18.75. Divide 18.75/0.75 to get the answer.
