Answer:

x = 7

Step-by-step explanation:

Let's join A & C . If points A ,B & C are collinear , then definitely B point's gonna lie on line segment AC .

So , AC = AB + BC

In the question , length of AC = 3x + 3 , length of AB = 2x - 1 ( or -1 + 2x)

& length of BC = 11.

We know that AC = AB + BC . So putting the given values here :-

3x+3 = 2x -1 + 11\\=>3x +3 = 2x+10\\

Solving this linear eqn. gives

3x + 3=2x+10\\=> 3x-2x=10-3\\=>x=7

Rick buys 3 CDs and 5 video games. The cost of one video game is $12.00 more than the cost of one CD. If Rick spends $164.00, wh
Dmitry [639]

Step-by-step explanation:

x = price per video game

y = price per CD

164 = 5x + 3y

and then we know

x = y + 12

now we can use this as substitute in the first equation :

164 = 5(y + 12) + 3y = 5y + 60 + 3y = 8y + 60

104 = 8y

y = $13

x = y + 12 = 13 + 12 = $25

so, each CD costs $13.

In the figure, AngleRQS Is-congruent-to AngleQLK. 3 lines are shown. Lines S P and K N are parallel. Line R M intersects line S
stepan [7]

Answer:

x=108

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m∠RQS≅m∠QLK -----> by corresponding angles

m∠KLM+m∠QLK=180° -----> by supplementary angles (consecutive interior angles)

we have that

m∠RQS=x° ----> given problem

so

m∠QLX=x°

m∠KLM=(x-36)° ----> given problem

substitute

(x-36)\°+x\°=180\°\\2x=180+36\\2x=216\\x=108
