The local newspaper has letters to the editor from 50 people. If this number represents 2% of all of the newspaper's readers, how many readers does the newspaper have?
Answer: The newspaper has 2500 readers.
Step-by-step explanation:
Given: The local newspaper has letters to the editor from 50 people.
This is the 2% of all newspaper readers.
Let x be the number of all newspaper readers.
Then. 2% of x= 50
[tex]\Rightarrow\ 0.02x=50\ \ [\text{To remove }\% \text{we divide number by 100}]\\\\\Rightarrow\ x=\dfrac{50}{0.02}=\dfrac{5000}{2}=2500\\\\\Rightarrow x=2500[/tex]
Hence, the newspaper has 2500 readers.

Answer:
-8
Step-by-step explanation:
Subtract 5 from both sides of the equation:
2+5=2−3
2+5−5=2−3−5
Simplify:
2=2−8
Subtract 2 from both sides of the equation:
2=2−8
2−2=2−8−2
Simplify:
0=−8
The solution to the algebraic expression has no solutions.
What is an algebraic expression?An algebraic expression comprises numbers, variables, and arithmetic operations with the aim of determining and finding a solution to the variables.
From the given expression, we have:
2x + 5 = 2x - 3
subtract 2x from both sides, we have:
2x -2x + 5 = 2x -2x - 3
5 = -3
Therefore, the solution algebraic equation has no solution since we don't have a variable to solve.

What is the justification for step 1 in the solution process? 15x − 8 = 14x + 13 Step 1: 15x = 14x + 21
Answer:
Step-by-step explanation:

The justification for Step 1 is the subtraction property of equality. Option B
What is the justification for step 1 in the solution process?The justification for Step 1 within the arrangement prepare, which changes the condition 15x − 8 = 14x + 13 into 15x = 14x + 21, is the subtraction property of uniformity.
The subtraction property of equality states that in the event that we subtract the same amount from both sides of an condition, the condition remains genuine. In this case, we are subtracting 14x from both sides of the condition to confine the term with x.
To clarify Step 1 utilizing the subtraction property of correspondence:
The condition 15x − 8 = 14x + 13 is given.
We need to disconnect the x term on one side of the condition. To do this, we got to dispose of the 8 on the cleared out side.
By subtracting 14x from both sides of the condition, we evacuate the 14x term from the correct side:
15x − 14x − 8 = 14x − 14x + 13
Simplifying:
x − 8 = 13
Now, the 14x term is dispensed with from the proper side of the condition.
To advance streamline the condition, we are able include 8 to both sides to dispose of the -8 term on the cleared out side:
x − 8 + 8 = 13 + 8
Simplifying:
x = 21
Now, we have effectively isolated the x term on one side of the condition.
Therefore, the justification for Step 1 is the subtraction property of equality (B).

What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( -8 , 6 )
Let the second point be Q ( 4 , -4 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( -4 - 6 ) / ( 4 + 8 )
Slope m = -5/6
Now , the equation of line is y - y₁ = m ( x - x₁ )
y + 4 = ( -5/6 ) ( x - 4 )
Subtracting 4 on both sides , we get
y = -5 x/6 - 4/6
Now , the ordered pair be ( 6 , 0 )
5x + 6y + k=0, passes through ( -6 , 10 )
So , ( -30 + 60 + k = 0 )
k = -30
And , the line is 5x + 6y - 30 =0
So , the ordered pair ( 6 , 0) satisfies the condition of the equation
Hence , the ordered pair is ( 6 , 0 )

In △ABC, BM is a median, △BMC is equilateral and MC = 3cm. Through M is drawn line l∥AB that intersects CB at point N. Find:
- m∠ABC
- The distance from C to AB
- The distance from l to AB
Answer:
m∠ABC = 60°
The distance from C to AB = 3 cm
The distance from l to AB = 1.5 cm
Step-by-step explanation:
The median of ΔABC = BM
The length of MC = 3 cm
Type of triangle given as ΔBMC = Equilateral triangle
Line MN is parallel to AB and passes through M intersecting CB at N
Given that BM is a median, we have;
MC = AM = 3 cm
BM = MC = CB = 3 cm, from ΔBMC = Equilateral triangle
CN = NB by midpoint theorem
∴ CB = CN + NB = 2·CN = 3 cm
The distance from C to AB = CB = 3 cm
The distance from C to AB = 3 cm
CN = 3/2 = 1.5
CN = NB = 1.5
The distance from l to AB = CN = 1.5 cm
The distance from l to AB = 1.5 cm
m∠ABC = m∠BMC = m∠MBC = 60° Interior angles of an equilateral triangle.
m∠ABC = 60°

Family Size: $ _____ per ounce.
Which one is a better buy (claim)?
How do you know (reasoning)?
Answer:
It would be better to buy the regular size

Two forces of 17.3 pounds and 42.5 pounds act on a body with an angle of 21.9 degrees between them. The force of 42.5 pounds acts on the body in the horizontal direction. Choose the correct approximation for the direction angle the resultant vector makes with the horizontal force.
a. 6.3
b. 21.9
c. 15.7
d. 10.9
The resultant vector makes a 6.3-degree angle with the horizontal force, the correct option is A.
What is the formula for determination of angle of the resultant vector ?The resultant angle between the vectors is given by
[tex]\rm \theta = tan^{-1} \dfrac{B sin\theta}{A +B cos\theta}[/tex]
The two forces have magnitude of 17.3 and 42.5 pounds.
The angle of the resultant vector is
[tex]\rm \rm \theta = tan^{-1} \dfrac{17.3\; sin\; 21.9}{42.5 +17.3 cos\;21.9}[/tex]
[tex]\rm \theta = tan^{-1}[/tex] (6.453/58.55)
[tex]\rm \theta[/tex] = 6.2886 degree = 6.3 degree.
Therefore, the resultant vector makes a 6.3-degree angle with the horizontal force.
