Step-by-step explanation:
m∠1 + m∠2 = 180°
(4x - 20) + (x - 15) = 180°
4x + x - 20 - 15 = 180°
5x - 35 = 180°
5x = 180° + 35°
5x = 215°
x = 215/5
x = 43°

Variable x in first equationStep-by-step explanation:
Given system
x = 5y - 1x + 2y = 13Variables in this system are x and y.
Isolating a variable means rearranging the equation so that a variable of our interest is on its own in one side of the equal sign.
We see variable x is isolated in the first equation.
In the second equation both of the variables are on the same side so they are not isolated.
Answer:
x
Step-by-step explanation:
x=5y-1--(1)The x variable is isolated here as it's solo on left side
Solve the equations
x+2y=13x=-2y+13--(2)Equate
5y-1=-2y+137y=14y=2x=10-1=9

Solve the equation 18+a= -50
Answers
a+18=-50
Subtract 18 from both sides
a=-68
Answer:
-68
Step-by-step explanation:
Subtract 18 from each side of the equation.
a + 18 = -50
-18 -18
Turn -50 - 18 into -50 + (-18) because you need to add the opposite.
a = -50 + (-18)
a = 68

Hometown Gym charges a $200 membership fee and $45 per month. Local Gym charges a $50 membership fee and $55 per month. Write an equation to represent the situation. After how many months will the total amount of money paid to both gyms be the same?
Answers
Answer:
=> membership fee = $50
=> monthly fee = $55
=> First month = 105$
=> 50 + 55(x)
=> 50 + 55 (15)
=> 50 + 825
=> 875
Workout gym
=> membership fee = $200
=> monthly fee = $45

How many vertices does this figure have?
Answers
8 verticles 4 at the bottom and 4 on the sides
Can someone help me i will give extra points
Answers
For the top part, both equations are vertical angles, so both equations will equal the same angle.
(4 + 23x) = (24x)
4 + 23x = 24x
4 = 24x - 23x
4 = x
Plug in x = 4 into both equations.
4 + 23(4) = 24(4)
4 + 92 = 96
96 = 96
Since x = 4 is a solution for both equations, the angle that is equal to both is 96 degrees.
Answer: 96 degrees is the angle--------------------------------------------------------------------------------------------------------------
For the bottom part, both equations lie on the same straight line, so adding both equations together will equal 180 degrees.
(x + 120) + (x + 80) = 180
x + 120 + x + 80 = 180
2x + 200 = 180
2x = 180 - 200
2x = -20 (don't worry about having a negative solution)
x = -10
Plug in x = -10 into both equations.
(-10) + 120 + (-10) + 80 = 180
110 + 70 = 180
180 = 180
Since x = -10 is a solution for both equations, the angle for equation (x + 120) is 110 degrees and angle for equation (x + 80) is 70 degrees.
Answer: Since the question asked to find a measure of the angle indicated in bold, the angle measure is 70 degrees.Please explain how to solve this and the answer

Looking at the letter arrangement in the problem B is similar to W
Set those equal to each other and solve.
X + 24 = 2x -2
Subtract x from both sides:
24 = x -2
Add 2 to both sides:
X = 26
Now replace x in the equation for B
2x -2 = 2(26)-2 = 52-2 = 50
B = 50 degrees
