Kyle divided his stamps
Marat540 [252]

Answer:

18

Step-by-step explanation:

Each page has 6 stamps. There are 3 pages. This is a simple multiplication problem, and so you do 3x6 to find the total number of stamps Kyle has. Thus, 3 times 6 is 18.

visual:

Page One: 6 stamps

Page Two: 6 stamps

Page Three: 6 stamps

6 + 6 + 6 = 18 (or just do 6x3)

What is the ratio the defines pi?
Rufina [12.5K]

Answer:

Step-by-step explanation:

By definition, pi is the ratio of the circumference of a circle to its diameter. In other words, pi equals the circumference divided by the diameter (π = c/d). Conversely, the circumference of a circle is equal to pi times the diameter (c = πd).

Use an inverse matrix to solve for the system of equations.
IrinaK [193]

Answer:

(-1, 7, 2)

Step-by-step explanation:

we suppose that ax + by + cz = d for the matrix

D = det [ 0    4     7] = 100

              -6   0    -2

               1    2     8

Dx= det [ 14    4     7] = - 100

               10   0    -2

               -3    2     8

Dy= det [ 0    14    7] = 700

               -6   10    -2

                1    -3    8

Dz = det [ 0    4    14] = 200

               -6   0     10

                1    2     -3

So the solution is:

x = Dx/D = -1, y = Dy/D= 7, z =Dz/D = 2

(-1, 7, 2)

have a good day!
