A. The sum of m∠1, m∠2, and m∠3 is 90°.
B. m∠1 + m∠2 + m∠3 = 180° 
C. Angle 1 and angle 3 form a straight angle 
D Angle 1, angle 2, and angle 3 all have the same measure.

The correct answer is letter B. m∠1 + m∠2 + m∠3 = 180° . The sum of interior angles of a triangle is 180 degrees.

If you subtract 12 from my number and multiply the difference by-3 the result is -54 what is my number

Alla [95]

first, make an equation:

$- 54 = - 3x - 12$

then, add twelve to both sides to remove it from the right:

$- 42 = - 3x$

then just divide by (-3) to get the value of x:

$x = 14$

Si p+ 2p+3p=12, ¿cual es el valor de 5p -1

Nutka1998 [239]

For this case we have the following equation:

$p + 2p + 3p = 12$

To solve we follow the steps below:

We add similar terms from the left side of the equation:

$6p = 12$

We divide between 6 on both sides of the equation:

$p = \frac {12} {6}\\p = 2$

Finally, we have to:

$5p-1 = 5 (2) -1 = 10-1 = 9$

Answer:

$p = 2\\5p-1 = 9$

The domain is the set { -2, 0, 2, 3}
discussion:
the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives -2, 0, 2, 3.
