Answers
Answer:
Angle 1 is 140.
Step-by-step explanation:
Set angle 1 and angle 3 equal to each other since they are congruent to each other to get this equation 20x+60=30x+20. Subtract 20x on both sides to get this equation 60 = 10x + 20. Subtract 20 on both sides to get to 40 = 10x. Divide 10 on both sides to get your x-variable which is 4. Since you are solving for angle 1, plug in the x-value to get 20(4)+60. You should get 140 degrees as your final answer.
please help!! which triangle is similar to ABC?
A. Triangle A
B. Triangle B
C. Neither
D. Both
Answers
Answer:
triangle A because the measurements would be the same. If you add 30 + 112, you get 150. Triangles add to 180, so the missing angle of the first one is 30.

19 more than 9 times a number is less than or equal to 163. Which of the following represents the solution set of this problem?
Answers
Answer:
x ≤ 6
Step-by-step explanation:
Let the unknown number be x;
9 times the number is expressed as 9x
9 more than 9 times a number is expressed as 9x + 9
9 more than 9 times a number is less than or equal to 163 is then expressed as;
9x + 9≤ 63
≤ is the less than or equal to sign
Find the solution;
9x ≤ 63 - 9
9x≤54
x ≤ 54/9
x≤ 6
Hence the required solution is x ≤ 6
If 9 is less than 3 times a certain number is 15 find the number. Please answer!!!!

Which shows the result of a correct substitution for the system y=2x+3 and 3x+2y=9?
Answers
Answer:
The result of the correct substitution gives:
x = 3/7 and y = 27/7
Step-by-step explanation:
From the given information:
y = 2x + 3 ---- (1)
3x + 2y = 9 ---- (2)
By using substitutional method
Substitute the value of y = 2x +3 into equation (2)
So,
3x + 2(2x + 3) = 9
3x + 4x + 6 = 9
7x = 9 - 6
7x = 3
x = 3/7
From equation (1), let replace the value of x to be 3/7
So,
y = 2x + 3
y = 2(3/7) + 3
y = 6/7 + 3
y = 27/7

Write the equation of a line in point-slope form that is parallel to the line y=2x-5 and goes through the point (-1,4)
Answers
(y-4) = 2(X+1)
Step-by-step explanation:
Hey there!
The given eqaution is; y = 2x-5.......(i)
Now; As the eqaution is in the form of y= mx+b.
Slope(m1) = 2.
As per the condition of parallel lines, slope of the 1st equation (m1) = slope of 2nd eqaution (m2).
Therefore, m1= m2= 2
Now, use one point formula for finding the eqaution of the line which passes through the point.
(y-y1) = m2(x-x1)
~ Put all values.
(y-4) = 2(X+1)
You can simply write upto here. But it you want to make it simplified form then, (look below)
~ simplify it.
y = 2x +2+4
The eqaution of the line which is parallel to y = 2x -5 and point (-1,4) is y = 2x + 6.
Hope it helps.....
Answer: y - 4 = 2(x + 1)
Step-by-step explanation:
The point slope form formula says that y - b = m(x-a) where m is the slope,b is the y coordinate of a given point , and a is the x coordinate of the same point.
Remember that parallel lines have the same slopes but different y-intercepts, meaning that m will equal to 2 because the slope for the line y=2x-5 is 2.
m will be 2, b will be 4 , and a will be -1.
y - 4 = 2(x - (-1) which reduces to
y - 4 = 2(x + 1)

Calculate the speed of a wave with a frequency of 2 Hz, amplitude of 3m, and a wavelength of 10m
Answers
10 * 2 = 20
The speed is 20 m/s
The speed of a wave is the product of the wavelength and its frequency.

Given
[tex]\lambda = 10m[/tex] --- the wave length
[tex]f =2Hz[/tex] --- the frequency
[tex]A = 3m[/tex] --- the amplitude
The speed of wave (v) is calculated as follows:
[tex]v =f\lambda[/tex]
Substitute values for f and [tex]\ambda[/tex][tex]\lambda[/tex]
[tex]v = 2Hz \times 10m[/tex]
[tex]v = 20ms^{-1}[/tex]
