∠A and ∠B are vertical angles with m∠A=x and m∠B=4x−30.
What is m∠A?
Answers
Answer:
m<A=10
Step-by-step explanation:
I left the image below to show my work of how i got to that answer. I hope this helps!
We know vertical angles have same measure!
Thus!
A = B
=> X = 4X -30
=> 3X = 30
=> X = 10
Thus measure of angle A is 10°Related Questions

Solve for x
8x+12=4x−16
Answers
Answer:
X= -7
Step-by-step explanation:
When you get X to one side and simplify you get -7
8x + 12 = 4 x - 16
Subtract 12 from both sides
8x = 4x - 28
Subtract 4x from both sides
4x = -28
Divide both sides by 4 to get rid of the coefficient so we know what x alone is equal to, instead of what we have currently which shows what 4 x's equals
x = -28/4
x = -7
Understanding the answer1x = - 7
One x is equal to - 7 units.
Hope this helps,

Answers
Answer:
G. 6 months
Step-by-step explanation:

What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, Barbara signed up for dance lessons at Dance Unlimited. She was charged $55 per month for lessons and a one-time recital fee of $165.
Let m be the no of months and f(m) is the total cost.
∴ f(m) = 55m + 165.
The equation represents the $495 total cost,
∴ 495 = 55m + 165.
55m = 330.
m = 330/55.
m = 6.

Work out the percentage change when 1.20 is increased to 1.80
Answers
Answer:
Step-by-step explanation:
PERCENT CHANGE
The percentage change from 1.20 to 1.80 is 50 %
Our percent calculator uses this formula:
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((1.80 - 1.20) / 1.20) * 100 = 50 %

3x square - 6x + 3=0
Answers
Answer: 1
Step-by-step explanation:
First you need to multiply 3 x 3 (9), because that's all 3 squared means.
Now the equation should be 9x-6x+3=0
Next we need to combine like terms. Do 9x - 6x which should give you 3x
Now your equations should be 3x+3=0
Now for the somewhat harder part...
Under the three (the one without the x) write -3 and under the zero write the same thing. the +3-3 cancels out so just put a line or something across it.
0-3= -3
so now you should have...
3x=-3 ignore the 3x, at this point it's useless in getting the answer because it would cancel out.
-3 divided by -3 is 1 because a negative (-) divided by a negative (-) equals a positive (+).
The answer should be x = 1

Step-by-step explanation:
You have to but the numbers in order than you cross each of the ends until you get the middle number/median
Answer: 9
Step-by-step explanation:
The median in math is basicly the middle of the list. First, put the list in order from least to greatest. Then, find the middle. If there is no middle, add the two numbers in the middle. Add them together, and divide the sum by two. The quotient is the median.
In this case, there is a middle. The middle is nine. Nine is the median.

A line has a slope of -2/3 and passes through the point -3 and eight what is the equation of the line
Answers
Answer:
Y=-2/3x+10
Step-by-step explanation:
We have the slope -2/3, so we can find the y intercept by plugging in the given coordinate (-3,8). if y=mx+b, 8=-2/3(-3)+b. If you simplify the equation, you would get 8=-2+b, and then you would get 10=b. 10 would then be the y intercept.

The length of rectangle is 5 cm greater than its width. The perimeter is 106cm. Find the dimensions of the rectangle.
Answers
Width-24 Length-29
Two sides of the rectangle are 5 cm bigger than the other two. So you would add the two 5 cm together (10cm). If you take the 10 cm off you (106-10) you will get a square. Then all you have to do is divide 96 by 4 (24), and add back on the two 5cm from the beginning to the length (29).
A rod with the density sigma(x) = 3 + sin(x) lies on the x-axis between x=0 and x = 3pi/4 find the center of mass of the rod
Answers
Answer:
10.7 grams
Step-by-step explanation:
hey there, again!
this is a similar process the mass is denisty*area HOWEVER keep in mind it's flat so the area is just x deltax while denisity is 3 + sin(x)
mass of rod = integral 0 to 3pi/4 of (3 + sin(x))*x deltax
= integral 0 to 3pi/4 of 3x + xsin(x) deltax
= 0 to 3pi/4 [3/2*x^2 + x(-cos(x)) + sin(x)]
= 10.7 grams

Determine if the conclusion that follows from the given statements below is valid. If valid which law was used?
1. if a number is a natural number then it is a whole number
2. if a number is a whole number then it is an integer
Conclusion : if a number is a natural number then it is an integer
Answers
Answer:
the conclusion is not valid
Answer: The conclusion is valid by the law of syllogism
The law of syllogism follows the basic form:
If P, then Q
If Q, then R
Therefore, if P then R
We can write it like this
[tex]P \to Q \\\\Q \to R\\\\\therefore P \to R[/tex]
We can think of it like starting at town P, moving to Q, then to R. Or we could go from P directly to R if we aren't worried about the town in the middle (town Q).
