Find the measure of the marked angles.
The measure of the angles is
___ degrees
Answers
Answer:
43°
(4x + 19)° = (6x + 7)° [vertically opposite angles are equal]
4x+19 = 6x+7
4x + 19 -7 = 6x
4x +12 = 6x
12 = 6x - 4x
12 = 2x
2x = 12
x = 12/2
x = 6
Now replace the x with 6
(4x+19)°
= (4×6+19)°
= (24+19)°
= 43°
(6x+7)°
= (6×6+7)°
= (36+7)°
= 43°
The measure of the angles is 43 degrees

What is the value of x in the equation 5 − 3x = −7?
Answers
Step-by-step explanation:
5 − 3x = −7
=> 5 + 7 = 3x
=> 12 = 3x
[tex] = > x = \frac{12}{3} [/tex]
=> x = 4 (Ans)
Given :
5 − 3x = −7⠀
To Find :
The required value of x .⠀
Solution :
[tex]\qquad \sf \: { \dashrightarrow 5 - 3x = - 7}[/tex]
⠀
Adding (–5) to both sides :
[tex]\qquad \sf \: { \dashrightarrow 5 + ( - 5) \: − 3x = −7 + ( - 5)}[/tex]
[tex]\qquad \sf \: { \dashrightarrow \: − 3x = - 12}[/tex]
⠀
Dividing both sides by 3 :
[tex]\qquad \sf \: { \dashrightarrow \dfrac{ - 3x}{3} = \dfrac{ - 12}{3} } [/tex]
[tex]\qquad \sf \: { \dashrightarrow − x = −4}[/tex]
⠀
Cancelling (–) from both sides we get :
[tex]\qquad {\pmb {\bf{ \dashrightarrow x = 4}}} \\ [/tex]

Therefore, The required value of x is 4.

Choose the correct description of each system of equations.
3x + y = 3
x - 2y = 4
Answers
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.
Given the system of equation expressed as:
3x + y = 3
x - 2y = 4
Solve simultaneosly;
3x + y = 3 ............. 1 * 1
x - 2y = 4 ...............2 * 3
_________________________
3x + y = 3
3x - 6y = 12
Subtract
y-(6y) = 3 - 12
7y = -9
y = -9/7
Substitute y = -9/7 into the equation to get x
x - 2y = 4
x - 2(-9/7) = 4
x + 18/7 = 4
x = 4 - 18/7
x = 3/7
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.

In wrestling you score points by performing certain moves. Escapes, takedowns, and nearfalls are moves you can perform to score points. An escapeis worth 1 point, a takedown is worth 2 points, and a nearfall is worth 3 points. Anahi scored a total of 240 points by completing 100 moves. She had 4 times as many takedowns as escapes. How many escapes, takedowns and nearfalls did she have?
Answers
Answer: Im gonna take you down like a sweet muffin.
The number of escapes, takedowns and nearfalls Anahi have is 6, 24 and 70 respectively.
How many escapes, takedowns and nearfalls did she have?escape is worth 1 point,
a takedown is worth 2 points, and
a nearfall is worth 3 points.
escape = x
takedown = y
nearfall = z
x + y + z = 100. (1)
x + 2y + 3z = 240. (2)
y = 4x. (3)
substitute (3) into both equation
x + 4x + z = 100
x + 8x + 3z = 240
5x + z = 100. (4)
9x + 3z = 240. (5)
Multiply (4) by 3
15x + 3z = 300 (6)
9x + 3z = 240. (5)
Subtract (5) from (6) to eliminate z
6x = 60
x = 60/6
x = 6
Substitute into (3)
y = 4x
y = 4(6)
y = 24
Therefore, from (1)
x + y + z = 100.
6 + 24 + z = 100
30 + z = 100
z = 100 - 30
z = 70

C. The sum of any rational number and any irrational number will always be an irrational number.
Explanation: Each time they assume the sum is rational; however, upon rearranging the terms if their equation, they get a contradiction (that an irrational number is equal to a rational number). Since the assumption that the sum of a rational and irrational number is rational leads to a contradiction, the sum must be irrational.

D. Any nonzero rational number times an irrational number is irrational.
Explanation: Assume r is nonzero and rational, and x is irrational. If rx = q, and q is rational, then x = q/r, which is rational. This is a contradiction.
