Okay, so to start, the bottom line equals 180°, so the two angles combined must equal that, right?

Next, come up with the equation:

(3x + 2) + (6x - 20) = 180

After that, you can combine the like terms to simplify it a little:

9x - 18 = 180

From there, add the 18 to both sides to cancel it out, which leaves you with:

9x = 198

Then just divide 198 by 9, and you'll get what X equals.

Hope it helps!

Answer:

x = 22

Step-by-step explanation:

The two angles form a straight line which is 180 degrees

3x+2 + 6x-20 = 180

Combine like terms

9x -18 = 180

Add 18 to each side

9x -18+18 = 180+18

9x = 198

Divide each side by 9

9x/9 = 198/9

x =22

Could someone help me with this question please!
torisob [31]
X + y = 56 ------------------(1)
x:y = 5:3
x/y = 5/3
3 x = 5 y
so, x = (5/3)y---------------(2)
sub (2) in (1)
x + y = 56
(5/3)y + y = 56
5 y + 3 y = 168
  8 y  = 168
  y  =  168 / 8  = 21
x = (5/3) x 21
  =  35
the value of x - y = 35 - 21
                          = 14

Which of the following is a factor of 10x2 − 11x − 6?
stepladder [879]

Answer:

5x + 2

Step-by-step explanation:

Given

10x² - 11x - 6

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 10 × - 6 = - 60 and sum = - 11

The factors are - 15 and + 4

Use these factors to split the x- term

10x² - 15x + 4x - 6 ( factor the first/second and third/fourth terms )

= 5x(2x - 3) + 2(2x - 3) ← factor out (2x - 3) from each term

= (x - 3)(5x + 2) ← in factored form

Thus 5x + 2 is a factor of 10x² - 11x - 6
