Allisa [31]

So the scale used was

1 inch = 6 feet

Step-by-step explanation:

Given

Length of library on drawing = 13 inches

Actual length of library = 78 feet

In order to find the scale we divide the actual length by the length of library on drawing.

So,

Scale = $Scale = \frac{Actual\ length}{Length\ on\ drawing}\\=\frac{78}{13}\\=6$

So the scale used was

1 inch = 6 feet

Step-by-step explanation:

So yeah there's 22 balls in total!

Then for the red balls, there are the balls numbered evenly: 6, 8, 10, 12, 14. So there's 5 even balls for red.

Then for the green balls: 8, 10, 12, 14, 16, there are also 5!

Using Cramer’s Rule, what is the value of x in the system of linear equations below?

cluponka [151]

Answer:

x = 8 is the answer

Step-by-step explanation:

In order to find the solution of Equations using Cramer's rule

we shall find matrices

D= $\left[\begin{array}{ccc}5&-3\\1&-2\end{array}\right]$ =

$D_{1} = \left[\begin{array}{ccc}4&-3\\-16&-2\end{array}\right]$

l D l = Determinant formed by coefficient of variables

Here l D l = 5X(-2) - 1X(-3)= -10+3 = -7

l D1 l = Determinant formed by replacing first column In D by numbers on the right side of the equations

Here l D1 l = 4X(-2)- (-16)X(-3)= -8-48 = -56

here x is given by $\frac{l D1 l}{l D l}$

x = $\frac{-56}{-7}$

x = 8
