How can you tell whether the sum/difference of two rational numbers will be positive or negative?

Answers

Answer 1

Answer:

When you are adding 2 integers you will get a sum that is negative

When adding 1 integer that is negative and 1 that is positive the sum will depend on how larger the absolute value is for  the 2 integers to tall if the answer is positive or negative

Elena and Lin are trying to solve 12x+3=72x+5. Describe the change they each make to each side of the equation.

Elena’s first step is to write 3=72x−12x+5.
Lin’s first step is to write x+6=7x+10.

Answers

Answer:

No Solution

Step-by-step explanation:

12x + 3 = 72x + 5

subtract 12x from both sides

end up with

3 = 72x - 12x + 5

subtract 12x to 72x

3 = 60x + 5

-5 from both sides

-8 = 60x

since x is a bigger number the answer would be NO SOLUTION

12x + 3 = 72x + 5

I do not understand lins logic

x + 6 = 7x + 10

subtract 6 from both sides

x = 7x + 4

move 7x to the other side

7x = 4

divide 7

x = 0.5

Also wrong because I get how lin got that answer

My way

12x + 3 = 72x + 5

-12 x from both sides

3 = 60x + 5

+5 to other side

8 = 60x

if the x was on the other side it would make sense

but it is not so the Answer is NO SOLUTION

Hope this Helped :)

The required solution of the given equation is given as -0.03.

Given that,
Elena and Lin are trying to solve 12x+3=72x+5. we have to describe the change they each make to each side of the equation.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Given equation,
12x+3=72x+5
Add and subtract 12x and 5 on both sides,
12x - 12x + 3 - 5 = 72x - 12x + 5 - 5
-2 = 60x
x = -2/60
x = 0.03

Thus, the required solution of the given equation is given as -0.03.

Students at the college are allowed to work on campus no more than 20 hours per week. The jobs that are available pay different rates, starting from $8.75 an hour. Students can earn a maximum of $320 per week.

Write at least two inequalities that could represent the constraints in this situation.

let h = hours worked
let r = the hourly rate in dollars

Answers

H is less than it equal to 20
R is greater than or equal to 8.75

The required system of inequalities is h ≤ 20 and r ≥ 8.75 which represents the constraints in the given situation.

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

College students are allowed to work on campus for no more than 20 hours a week. The listed jobs pay a range of rates beginning at $8.75 per hour. Students can earn up to $320 every week.

Let h represents hours worked

Let r represents the hourly rate in dollars

According to the given situation, the required inequalities would be as:

h ≤ 20 and r ≥ 8.75

Therefore, the required system of inequalities is h ≤ 20 and r ≥ 8.75 which represents the constraints in the given situation.

Answer:

what is a quartile?

Step-by-step explanation:

Answer:

The interquartile range is Q3 minus Q1, so IQR = 6.5 - 3.5 = 3.

Step-by-step explanation:

consider the following numbers: 1, 3, 4, 5, 5, 6, 7, 11. Q1 is the middle value in the first half of the data set. Since there is an even number of data points in the first half of the data set, the middle value is the average of the two middle values; that is, Q1 = (3 + 4)/2 or Q1 = 3.5. Q3 is the middle value in the second half of the data set. Again, since the second half of the data set has an even number of observations, the middle value is the average of the two middle values; that is, Q3 = (6 + 7)/2 or Q3 = 6.5.
