What is the value of x in the equation 5 − 3x = −7?
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.
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?
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

b. From any point on the graph, he counts up 2 then right 3 to end up on the line again
c. From any point on the graph, he counts down 2 then left 3 to end up on the line again.
d. I don't know.
Answer:
a. From any point on the graph, he counts down 2 then right 3 to end up on the line again.
Step-by-step explanation:
The slope is -2/3.
-2/3 = 2/-3
slope = rise/run
rise/run = -2/3
Count down 2 and right 3.
rise/run = 2/-3
Count up 2 and left 3

Answer:
See below
Step-by-step explanation:
f(x) = -2x + 2
Put x = 1
f(1) = -2(1) + 2
f(1) = -2 + 2
f(1) = 0
Put x = 0
f(0) = -2(0) + 2
f(0) = 2
Put x = -1
f(-1) = -2(-1) + 2
f(-1) = +2 + 2
f(-1) = 4
Put x = 2
f(2) = -2(2) + 2
f(2) = -4 + 2
f(2) = -2

Find the measure of the marked angles.
The measure of the angles is
___ degrees
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
