Answer:

(3x -5)°+ (2x- 15)°=180°[sum of co- Interrior angles of a triangle is 180°]

or, 3x- 5 + 2x - 15=180°

or,5x - 20 = 180°

or, 5x = 180°+20

or, x = 200÷ 5

•°•x = 40°

Answer:

X = 40

Step-by-step explanation:

3x + 2x -5 -15 = 180

5x + -20 = 180

then u add 20 on both sides

5x + 0 = 200

ya the 0 is not necessary but I was showing u add 20 on both sides lol

then u divide 5 on both sides to get the x by itself

x = 40

Hope this helps dude ^-^

Sanya makes a pattern of values for x and a pattern of values for y which ordered pair continues the patterns and has an x value
Mama L [17]

Answer:

C. (6,9)

Step-by-step explanation:

If you look at the way the x is going up. It goes by two digits every time. 0 -> 2

and 2 -> 4. While the y goes up by three every two x. 0 -> 3 and 3 -> 6. Which means if you make x = 6 than you would have to multiply 3 by 3 to equal 9.

Combine the radicals. 3√5-8√5+2√5
weeeeeb [17]

Answer:  -3\sqrt{5}

-3 times the square root of 5

=============================================

Explanation:

Let x = \sqrt{5}

Replace all the root 5 terms with x and we go from

3\sqrt{5}-8\sqrt{5}+2\sqrt{5}

to

3x-8x+2x

From here, combine like terms to get

3x-8x+2x = -5x+2x = -3x

and the last thing to do is replace the x with sqrt(5)

-3x = -3\sqrt{5}

Meaning that,

3x-8x+2x = -3x

3\sqrt{5}-8\sqrt{5}+2\sqrt{5} = -3\sqrt{5}
