Answer:

Step-by-step explanation:

The 3 angles must add up to 180. So

6x + 4x + 2x = 180

12x = 180

x = 15

Plug this into all the angles and you have your answers

Answer:

Step-by-step explanation:

The sum of a triangles angles is always 180 degrees.

2x+4x+6x=180

12x=180

x=15

A=6x=6(15)=90 degrees

B=2x=2(15)=30 degrees

C=4x=4(15)=60 degrees

Cross multiply

(3x - 1)(4x + 5) = (2x + 6)(6x - 4)

12x^2 + 11x - 5 = 12x^2 + 28x -24

Solve for x

-17x = -19

x = 19/17

You have a wire that is 38 cm long. You wish to cut it into two pieces. One piece will be bent into the shape of a square. The o

Drupady [299]

Answer:16.71 cm

Step-by-step explanation:

Given

Length of wire L=38 cm

One piece is bent in the form of square and another in the form of circle

let x be the length of circle

therefore length of square side $\frac{38-x}{4}$

A=total area of square and circle

radius of circle $r=\frac{x}{2\pi }$

area of circle $A_c=\pi r^2=\pi \times (\frac{x}{2\pi })^2$

Area of square $A_s=(\frac{38-x}{4})^2$

$A=\pi \times (\frac{x}{2\pi })^2+(\frac{38-x}{4})^2$

To get the minimum value of A we get

$\frac{\mathrm{d} A}{\mathrm{d} x}=\frac{2x}{4\pi }-\frac{2(38-x)}{16}$

$\frac{\mathrm{d} A}{\mathrm{d} x}=0$

$\frac{x}{4\pi }=\frac{38-x}{16}$

$x=\frac{38\pi }{4+\pi }$

Therefore circumference of circle

$x=\frac{38\pi }{4+\pi }=\frac{119.396}{7.142}=16.717 cm$

How to solve system of equation from a table

faust18 [17]

Answer:

Look for the same entry in both (all) tables.

Step-by-step explanation:

We assume here that the system of equations consists of two equations in two variables. If there are more equations in more variables, the general approach is the same.

A "solution" to a system of equations is a set of variable values that satisfies all equations of the system simultaneously. A table for one equation will generally list sets of variable values that satisfy that equation. When the same set of values appears in the table for each of the equations, then that set of values is the solution.

Example

The attachment shows tables for two equations:

y = 2x
y = x+3

Highlighted are the table entries that are the same for both equations. This is the solution to the system of equations. (x, y) = (3, 6) satisfies both equations:

6 = 2·3
6 = 3+3

cd city sells 5 cds for 49$ music land sells 8 cds for $59.50 which store is the better place to buy cds

Dmitriy789 [7]

Answer:

Music land has the better deal with each CD costing only $7.44 compared to $9.80 at CD City.

Step-by-step explanation:

In order to find the price per CD, you must divide the cost by the number of CDs in the bundle.

Music Land

$59.50/8 CDs = $7.44 per CD

CD City

$49/5 CDs = $9.80 per CD

Therefore, we know that Music Land is a better deal.
