Angle KLN is congruent to angle JNM because they are vertical angles and vertical angles are congruent.
Set up am equation to make them equal to each other.
5x+2 = 3(x+14)
Distribute 3 to the values in the parentheses
5x+2 = 3x+42
Subtract 3x from both sides
2x +2 = 42
Subtract 2 from both sides
2x = 40
Divide both sides by 2
X=20

Substitute 20 for x in the angle KLN
3(20+14)
Simplify parenthesis
3(34)
Multiply
KLN =102 degrees

Please tell me the answer! I'm crying in confusion! :(

First, change the fractions to a common denominator, which is 21. 

so 3/7 * 3/3  = 9/21

1/3 * 7/7 = 7/21

Add the two together

9/21 + 7/21 = 16/21

Then take 21/21 - 16/21 = 5/21

There is 5/21 of the pizza left.

A fitness club has two options, one for members and one for nonmembers. Members pay a one-time registration fee of $12 plus $8 p
Liula [17]

Answer:

See below.

Step-by-step explanation:

Let's look at the cost for members (C1) first.  Let x be the number of visits.

C1(x) = 12 + 8x

For non-members (C2), we can do the same.

C2(x) = 10x

You can graph these two equations.

x        C1         C2

0       12          0

1        20        10

2       28        20

3       36        30

4       44        40

5       52        50

6       60        60

7       68        70

Let's make the two equations equal, to find out where the benefit is the same.

12 + 8x = 10x

2x = 12

x = 6

Up to 5 visits, the non-member cost is better.  At 6 visits, there's the same price.  For more than 6 visits, the member cost is better.

3х – 6+1 = - 2x – 5+5х​
marysya [2.9K]

Answer:0=12

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

3x-7=3x-5

Combine like terms:

3x-3x=7+5

0=12
