Explain how to use a number line to show that opposite quantities combine to make zero.
did I do this correctly??
Yes your answer is correct.
Yes, you did it correctly.
We have two opposite quantities.
We have to show that opposite quantities combine to make zero.
What is a Vector quantity ? What are equal and opposite Vectors?Any quantity with both magnitude and direction is called vector quantity.
Two vectors are said to be equal and opposite if they have same magnitude and angle of 180 degrees between them.
According to the question -
Assume a number line and mark a number say 'x' after 0 and a number
'-x' before zero. These two numbers represent the quantities with same magnitude. And it can be easily seen that the angle between line from center point 'O' to 'x' and the line from 'O' to '- x' is 180 degrees. Hence, these two equal and opposite quantities which will give a resultant value of = + x + (- x) = + x - x = 0
And you also did it correctly ( You have taken 5 and -5).

Step-by-step explanation:
is 2/5-(-5/6) a positive, negitive, or zero
Answer:
Positive
Step-by-step explanation:
[tex]\frac{2}{5}-(-\frac{5}{6})[/tex]
Remember, a number minus the negative of a number would be equal to that first number plus that second number but not negative. In other words:
a - (-b) = a + b
So:
[tex]\frac{2}{5}-(-\frac{5}{6})=\frac{2}{5}+\frac{5}{6}[/tex]
The sum of two positive numbers would be a positive number. Because of this, we can see that the value would be positive.

A square field has 3844 m² of land what is the width of the field?
a = one side of a square
The area of a square = a^2
In our problem,
Area = 3844 m^2
a = ?
Let's plug our values into the area equation.
3844 m^2 = a^2
Take the square root of both sides
62 m = a
The width of the field is 62 meters

The sum of three consecutive even integers is –78. What are the integers?
Describe how you would use the strategy of writing an equation to solve the given problem.
hiya! i've been swamped on this question for a good bit now. i know what the answer is, but i'm not sure how to get there. Why are my integers n, n+2, and n+4? how do you find out those are the ones that you need to use? what's n? how does it work out the way it does? why and how do i get this answer? i just don't understand the process or the mind behind it and i need it to be broken down for me. Thank you!!
Step-by-step explanation:
(Hope this explanation can ease your mind a little if possible! Alright let's go! :D)
Let n be the middle of the 3 consecutive even integers. Therefore, (n - 2) and (n + 2) are the smallest and largest of the 3 numbers respectively.
We know that (n - 2) + n + (n + 2) = 78,
so 3n = 78, and n = 78/3 = 26.
Since the middle number is 26, the smallest number is 26 - 2 = 24 and the largest number is 26 + 2 = 28.

Mrs. Sanchez asked her students to
classify the following value as rational or
irrational:
0.62581
Ryan thinks the value is irrational because
the decimal does not have a pattern.
Do you agree with Ryan? Why or why not?
Answer:
The answer is that it is a rational number because it is a terminating decimal
Step-by-step explanation:
0.62581 is a rational number.
What are rational numbers and irrational numbers?
Rational numbers are numbers that can be written as the ratio of two integers. For example: 1/2, 3/4, are rational numbers.
Irrational numbers, any real number that cannot be expressed as the quotient of two integers—that is, p/q, where p and q are both integers. For example, there is no number among integers and fractions that equals Square root of√2.
Now the given number is,
0.62581
Now here we see that the numbers after decimal are terminating and non-repeating.
Also the digit after decimal stops.
Hence the number 0.62581 is rational.

Heather received grades of 80, 75, and 86 on 3
math 1 tests. What is lowest grade she can
receive on the next test if she wants her average
for the four test to be at least an 82?
Define your variable
Answer:
87
Step-by-step explanation:
We know Heather recieved grades of 80, 75 and 86.
Let's find her average on those 3 tests.
80 + 75 + 86 = 241 Since there are 3 tests we divide by 3.
241/3 = 80.3333 Is her aveerage on the first 3 tests.
She need to average 82 so we can write an equation with t being the score on her 4th test.
[tex]\frac{80 + 75 + 86 + t}{4} = 82[/tex]
[tex]\frac{241 + t}{4} = 82[/tex] Multiply each side by 4
([tex]\frac{241+t}{4}[/tex]) * 4 = 82 * 4 4 on the left will cancel
241 + t = 328 Subtract 241 from each side
241 - 241 + t = 328 - 241
t = 328 - 241
t = 87
Heather must get an 87 to have an average score of 82.

A. It has 2 terms and a degree of 2.
B. It has 2 terms and a degree of 3.
C. It has 4 terms and a degree of 2.
D. It has 4 terms and a degree of 4.
Answer:
B:It has 2 terms and a degree of 3
Step-by-step explanation:
Hope this helps!
The polynomial 3x²y² − 5xy² − 3x²y² + 2 x 2 after fully simplified has 2 terms and a degree of 2, so option A is correct.
What is polynomial?A polynomial is a mathematical expression that solely uses the operations of addition, subtraction, multiplication, and positive-integer powers of variables. It is made up of indeterminate (also known as variables) and coefficients.
Given:
3x²y² − 5xy² − 3x²y² + 2 x 2
Simplify the above expression,
3x²y² − 5xy² − 3x²y² + 2 x 2 = -55xy² + 4
As you can see from the expression, it has the two-term and highest degree of 2
Therefore, the polynomial 3x²y² − 5xy² − 3x²y² + 2 x 2 after fully simplified has 2 terms and a degree of 2.

The club supplies 40 new balls for each player which cost $1 each. Each player pays $300 for the lessons. The club must pay each instructor $1,000 for conducting the lessons, and there must be at least 1 instructor for every 6 players. Which amount of players and instructors meets these requirements and still gives the club a net profit?
Answer:
4 players and 1 instructor
Step-by-step explanation:
If all 4 players pay $300 each, that equals $1,200. The instructor will get $1,000 of it. That means there is $200 left. They need 40 balls per player. Each ball is $1, so that's $40 per player. 40 x 4= 160 200-160 = 40 The club will have $40 left.
