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.
Juan graphed a line with a slope of -23
How does Juan count the slope from any point on the graph?
a. From any point on the graph, he counts down 2 then right 3 to end up on the line again.
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.
Answers
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: a. From any point on the graph, he counts down 2 then right 3 to end up on the line again.

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

In class today, we had 98 notebooks and 70 children.If each child gets two notebooks, how many more notebooks will we need?
Answers
Answer:
42
Step-by-step explanation:
times 70 by two to get how many notebooks needed total.
70*2=140
subtract how many notebooks you already had.
140-98=42
The no. of notebooks we need more will be equal to 42 notebooks.
It is given that no. of notebooks available is 98 and there are 70 children in class.
We have to find no. of notebooks needed more if each child gets two notebooks.
What is algebra ?
Algebra is the branch of mathematics that deals with various symbols and the arithmetic operations and the symbols are called variables.
As per the question ;
No. of notebooks we had in class = 98 notebooks
And
Total no. of children = 70 children
The no. of notebook each child gets = 2 per child
So ;
70 children will get no. of notebooks ;
= 70 × 2
= 140 notebooks
The no. of notebooks we need will be ;
= 140 - 98
= 42 notebooks
Thus , the no. of notebooks we need will be equal to 42 notebooks.

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.
Answer:
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.

E. The system of polynomials is almost the same with the system of whole numbers.
Explanation: We count with and use a base 10 (decimal) system. Polynomials such as the function above are a “base x” system.
