<u>Given</u>

  • The mean temperature for the first 4 days = -12°C
  • The mean temperature for the first 5 days = -13°C

<u>To find</u>

  • The temperature on the 5th day

<u>Solution</u>

  • Total of 4 days = 4*(-12) = -48°C
  • Total of 5 days = 5*(-13) = -65°C

<u>The difference is the temperature on the 5th day:</u>

  • -65 - (-48) = -17°C

Three-eighths of the students in a certain class are males and 3/5 of the male
Mrrafil [7]

Answer:

3/5 of the students in the class are not in accounting majors

Step-by-step explanation:

The total number of males in the class is 3/8

3/5 of them are accounting majors

The ones who are not in accounting majors are;

3/8 - 3/5 = 9/40

The total number of female students in the class is;

8/8 - 3/8 = 5/8

1/4 of them are accounting majors

The ones who are not in accounting majors are;

5/8 - 1/4 = 3/8

Total number of students not in accounting majors;

9/40 + 3/8

= 24/40

= 3/5

Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution.
Len [333]

Answer:

only one solution

Step-by-step explanation:

Complete question:

<em>Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution. 2x − y = 2 3x + y = −6 one and only one solution infinitely many solutions no solution Find the solution, if one exists. (If there are infinitely many solutions, express x and y in terms of the parameter t. If there is no solution, enter NO SOLUTION.) (x, y) </em>=

Given the expression

2x − y = 2 .... 1

3x + y = −6  ..... 2

We are to determine the number of solution the equation has:

Add equation 1 and 2

2x + 3x = 2 - 6

5x = -4

x = -4/5

Substitute x = -4/5 into 1

From 1: 2x − y = 2 .... 1

2(-4/5) - y = 2

-8/5 - y = -2

-y = -2+8/5

-y = -10+8/5

-y = -2/5

y = 2/5

<em>Since the value of x and y are just 1 hence the system of equations has ine solution</em>
