Answer:
-71
Step-by-step explanation:
let 'n' = a number
2(143 + 2n) = 0n + 2
2(143 + 2n) = 2
143 + 2n = 1
2n = -142
n = -71

5. Find mTOS in the figure below.
Answer:
See below:
Step-by-step explanation:
Hello! I hope you are having a nice day!
We can solve this problem in a single step, that is using theory and a bit of algebra/elementary math.
We can start off by looking at the problem. We see that angles UOT and angle TOS both add up to 180 degrees
Since we know this, we can form the equation [tex]<TOS=180-128[/tex]
Therefore, we know that <TOS is 52 degrees.
We can test this by adding up 52 and 128 and we should get 180.
[tex]128+52=180?\\180=180[/tex]
Therefore, [tex]<TOS=52[/tex] degrees.

Answer: 6.25
Step-by-step explanation:
How many negative integers $m$ satisfy the inequality $\dfrac{3}{m} \le -\dfrac27$?
Answer:
10
Step-by-step explanation:
The restriction m < 0 means we can multiply by -7m/2 without changing the direction of the inequality symbol
[tex]\dfrac{3}{m}\le-\dfrac27\\\\-\dfrac{21}{2}\le m\qquad m<0}[/tex]
Then the solution is the number of negative integer values between -10.5 and 0. There are 10 negative integer values of m that satisfy the inequality.

the sum of the interior angle in a polygon is 40,500° what is the number of sides in the regular polygon
Answer:
227 sides
Step-by-step explanation:
The sum of the interior angles of a convex polygon is S=180(n-2) where n is the number of sides. If S=40500, then we have our equation 40500=180(n-2) and we can solve for n:
40500 = 180(n-2)
225 = n-2
227 = n
Therefore, the number of sides in the regular polygon is 227.

Haynes High School chartered buses for 60 students to go on a field trip. Valley High School chartered buses for 80 students.
*The total cost of the buses was the same for the two schools
*Students from Valley High School paid $5 less than students from Haynes High School.
What was the cost per student for Haynes High School?
A. $5 B. $15 C. $20 D. $40
Answer: $20
Step-by-step explanation:
Let 'x' be the cost of a ticket at Haynes
Let 'y' be the cost of a ticket at Valley
Since the total cost from both schools are the same, we can write it as:
[tex]60x=80y[/tex]
Since the cost of tickets at Valley was $5 less than Haynes, we can write it as:
[tex]y=x-5[/tex]
Now we have two equations, we can use to substitute into the other expression:
[tex]60x=80y[/tex]
[tex]60x=80(x-5)[/tex] we substitute y in this equation with the other equation
[tex]60x=80x-400[/tex]
[tex]-20x =-400[/tex]
[tex]x = 20[/tex]
Therefore the cost of the ticket at Haynes is $20 and the cost of the ticket at Valley is $15.

The weight of each fountain pen manufactured in a factory must be 10g with a tolerance of 2g. Pens that are not within the tolerated weight must be thrown away. Write an inequality that can be used to assess which pens are tolerable (w is the weight of the pen)?
According to the information given, the absolute value inequality that can be used to assess which pens are tolerable is:
[tex]|w - 10| \leq 2[/tex]
The absolute value function measures the distance of a point to the origin, and is defined by:
[tex]|x| = x, x \geq 0[/tex][tex]|x| = -x, x < 0[/tex]The weight must be of 10g, with a tolerance of 2g, which means that the absolute value of the difference between the weight w and 10g must be of at most 2g, hence the inequality is:
[tex]|w - 10| \leq 2[/tex]

convert the following equation into standard form. y= -5x/6+2
Answer:
5x + 6y = 12
Step-by-step explanation:
The standard form of a linear equation is Ax + By = C.
Multiply both sides by 6
6y = 6(-5x/6 + 2)
Simplify the right side
Simplify
6(−5x/6+2)
Apply the distributive property = a ( b + c ) = ab + ac
6y = 6( −5x/6) + 6 ⋅ 2
Cancel the common factor of 6
Move the leading negative in −5x/6 into the numerator
6y = 6 −5x/6 + 6 ⋅ 2
Cancel the common factor 6
Rewrite the expression
6y = −5x + 6 ⋅ 2
Multiply 6 by 2
6y = -5x + 12
Move all terms containing variables to the left side of the equation
Add 5x to both sides of the equation.
6y + 5x = 12
Reorder 6y and 5x
5x + 6y = 12

Ben reads 6 pages of a book in 8 minutes, 9 pages in 12 minutes, and 30 pages in 40 minutes. If m represents the number of minutes and p represents the number of pages, which equation represents the number of pages Ben reads per minute?.
The equation which represents the number of pages Ben reads per minute is p = 0.75m
Given:
6 pages of a book in 8 minutes
9 pages in 12 minutes
30 pages in 40 minutes
Number of minutes = m
Number of pages = p
Pages per minute = 6 pages ÷ 8 minutes
= 6/8
= 0.75 pages per minute
The equation:
p = 0.75m
Therefore, the equation which represents the number of pages Ben reads per minute p = 0.75m
