Answer:

Step-by-step explanation:

Sum of exterior angle of a polygon is equal 360°

: 2x + (x+4) + (x+16) + (x+10) + 2x + (x+10) = 360°

2x + x + x + x + 2x + x + 4+16+10+10 = 360°

8x + 40 = 360

8x = 360 - 40

8x = 320

x = 320/8

x = 40°

Kayla is selling lemonade for $1 and cookies $0.50 outside of her house in order to earn enough money to buy a bike that costs $

Leto [7]

Answer:

Step-by-step explanation:

Step one:

Cost of one lemonade= $1

Cost of one Cookie= $0.5

Cost of bike= $249

Step two

let the number of cookie be C

and the number of lemonade be L

The total cost expressed as a function of the numbers of lemonade and cookie is

249=C+0.5L------------1

we are told that

C=L/2----------------------2

Therefore substitute C=L/2 we have

249=L/2+0.5L

249=0.5L+0.5l

249=L

The system of equation is

249=C+0.5L------------1

C=L/2----------------------2

You have learned three ways for solving systems of equations: graphing, substitution and elimination.

ra1l [238]

Answer:

Elimination

Step-by-step explanation:

Graphing takes too long, substitution can sometimes complicate things quickly, therefore I would use elimination as my prime method of solving systems of equations.

Point G is on line segment FH. Given FG=5x+2,GH=3x-1, and FG=9, determine the numerical length of FG

stealth61 [152]

Given:

FG=5x+2

GH=3x-1

FG=9

Let us draw the line segment as follows,

Equating the length of FG, we get,

$\begin{gathered} 5x+2=9 \\ 5x=9-2 \\ 5x=7 \\ x=\frac{7}{5} \end{gathered}$

Substitute the value of x in the given value of GH,

$\begin{gathered} GH=3x-1 \\ =3(\frac{7}{5})-1 \\ =\frac{21}{5}-1 \\ =\frac{16}{5} \\ =3.2 \end{gathered}$

And the total length FH is,

$\begin{gathered} FH=FG+GH \\ =9+3.2 \\ =12.2 \end{gathered}$

Hence, the lengths are,

$\begin{gathered} FG=9 \\ GH=3.2 \\ FH=12.2 \end{gathered}$
