Answer: 1.75

Step-by-step explanation:

5.25 / 3 = 1.75

1.75 x 4 = 7

1.75 x 7 = 12.25

Suppose that a group of 10 students are to be assigned to four dorm rooms: a single, a double, a triple and a quad. How many way
Nesterboy [21]

Answer:

Total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200

Step-by-step explanation:

We have given number of students = 10

These 10 students are assigned to four dorm rooms a single, a double, a triple and a quad

So number of ways to assigned single student =^{10}C_1=\frac{10!}{1!9!}=10\\

Now left student = 10 -1 = 9

So number of ways to assigned double student =^{9}C_2=\frac{9!}{2!7!}=36

Now left student = 9-2 = 7

So number of ways to assigned triple student =^{7}C_3=\frac{7!}{2!4!}==70

Now left student = 7 - 3 = 4

So number of ways to assigned quad student =^{4}C_4=\frac{4!}{4!0!}=1

So total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200

Twelve is the same as two-thirds a number diminished by two.
Nadusha1986 [10]

12 = 2/3(x - 3)

<em><u>Distributive property.</u></em>

12 = 2/3x - 2

<em><u>Add 2 to both sides.</u></em>

14 = 2/3x

<em><u>Multiply both sides by 3.</u></em>

42 = 2x

<em><u>Divide both sides by 2.</u></em>

21 = x

The value of x is equal to 21.
