13x−4=−36−27x+12: Distributive property  

13x−4=−24−27x: Combine like terms

<h2>Answer with Step-by-step explanation:</h2>

13x−4= −9(4+3x)+12    (Given)

13x−4= −36−27x+12     (Distributive property:  -9(4+3x)= -36-27x)

13x−4=  −24−27x   (combining like terms on each side:  -36+12= -24)

40x−4=−24    (Addition Property of Equality: adding 27x on both sides )

40x= −20     (Addition Property of Equality:   adding 4 on both sides )

x= −1/2      (Division Property of Equality:  dividing both sides by 40)

vector w has magnitude 25.0 and direction angle 41.7 degrees. Calculate the horizontal and vertical components of w
11Alexandr11 [23.1K]

Consider the attached picture. It represents a vector, centered in the origin with angle 41.7 degrees, and a circumference with radius 25, centered in the origin.

As you can see, the horizontal and vertical components of the vector correspond to the lengths of segments OD and OC, respectively.

You might recognize this scenario from you trigonometry class: if the circle had radius 1, we would have

OD=\cos(41.7),\quad OC=\sin(41.7)

Since the circle has radius 25, we have to scale those coordinates:

OD=25\cos(41.7),\quad OC=25\sin(41.7)

= 1076

b) no. of pages printed in 9 min = 294×9

= 2646

What is the probability that a randomly chosen male voter is a registered Democrat? Round your answer to the nearest tenth of a
grin007 [14]

Answer:

49%

Step-by-step explanation:

Well, you would just divide the "male democrat" category and the "male total" category and then move the decimal over 2 spaces, because you need to multiply by 100 to turn your answer into a percent, so:

\frac{600}{1222}=0.49

Then once you multiply by 100, or move the decimal to the left 2 spaces, it becomes:

49%
