The sum of three consecutive even integers is 72. Let x represent the first integer x+2 represent the second integer and x+4 rep

satela [25.4K]

72 = x + x+2 + x+4

72 = 3x+6

66 = 3x

x = 66/3 = 22

1st number = 22

2nd number = 22+2 = 24

3rd number = 22+4 = 26

il63 [147K]

Answer:

Number of students(n1)= 4,402

Step-by-step explanation:

Giving the following information:

Number of students= 4,512

Declining rate= 2.5%

<u>To calculate the number of students next year, we need to use the following formula:</u>

Number of students (n+x)= number of students (n0) / [(1+declining rate)^(n+x)

x= number of years

Number of students(n1)= 4,512/1.025

Number of students(n1)= 4,402

Systems of linear equations iready quiz

saw5 [17]

Answer:

<h2>One solution.</h2>

Step-by-step explanation:

The given question is

<em>Does the following system have One Solution, No Solution, or Infinite Solutions. </em>

<em />

To solve this system, we just need to multiply the first equation by -1, and then sum those equations.

$-y = -4x - 8\\y = -5x + 3$

$0=-9x-5\\5=-9x\\x=-\frac{5}{9}$

Then, we use this value to find the other one

$y=4x+8\\y=4(-\frac{5}{9} )+8\\y=-\frac{20}{9}+8\\y =\frac{-20+72}{9} \\y=\frac{52}{9}$

As you can observe, the system of equations have a unique solution.

Therefore, the answer is one solution.
