What is the length of the green route in miles?

The correct answer is G) 4.5 mi.

Let b be the length of the blue route and g be the length of the green route:

6g+5b=52
12g+13b=119

We will use elimination to solve this.  We will make the coefficients of g equal by multiplying the first equation by 2:
2(6g+5b=52) → 12g+10b=104

Now we will subtract the second equation from this:
  12g+10b=104
-(12g+13b=119)
-3b=-15

Divide both sides by -3, and we have
b = 5

Substitute this into the first equation:
6g+5(5)=52
6g+25=52

Subtract 25 from both sides:
6g=27

Divide both sides by 6:
g = 27/6 = 4.5

The green route is 4.5 miles long.

This is a system of equation problem. You have to set up 2 different equations and then solve them.

You could have:

6g + 5b = 52
12g + 13b = 119

To solve them, you can use graphing, substitution or elimination.

Either way, you will find the blue route is 5 miles and the green route is 4.5 miles.

Simplify and find the perimeter of the triangle
lbvjy [14]

Answer:

2x - 19

Step-by-step explanation:

Perimeter = sum of sides

First let's simplify each side

We can simplify each side by using distributive property. Distributive property is where you multiply the number on the outside of the parenthesis by the numbers on the inside of the parenthesis.

2(x + 5)

Distribute by multiplying x and 5 by 2

2 * x = 2x and 2 * 5 = 10

2x + 10

1/2(4x + 8)

Distribute by multiplying 4x and 8 by 1/2

1/2 * 4x = 2x and 1/2 * 8 = 4

2x + 4

-3(2x + 11)

Distribute by multiplying 2x and 11 by -3

-3 * 2x = -6x

-3 * -33

-6x - 33

Finally add all the simplified expressions ( remember that they represent the side lengths of the triangle )

2x + 10 + 2x + 4 - 6x - 33

Combine like terms

2x + 2x - 6x = -2x

10 + 4 - 33 = -19

Perimeter: -2x - 19

Can someone help? This is so hard
Sunny_sXe [5.5K]

Answer:

#1 x = 31°

#2 x = 125°

Step by Step Explanation:

#1

  • By the theorem of intersecting secants outside of the circle, we have:

  • x=\frac{1}{2}(103\degree-41\degree)

  • \implies x=\frac{1}{2}(62\degree)

  • \implies \red{\bold{x=31\degree}}

#2

  • By the theorem of intersecting chords, we have:

  • x=\frac{1}{2}(96\degree+154\degree)

  • \implies x=\frac{1}{2}(250\degree)

  • \implies \purple{\bold{x=125\degree}}
