The number that you are looking for is 540

7 0

Since the number is divisible by 5, we can go up by 5's, starting from 500.
Since the number is NOT an even number, we can skip the numbers 510, 520, 530, so on.
I kept going up, 505, 515, 525, 535, 545, etc.. and tried to divide them by 9. 585 is the only number that is divisible by 9. It is an odd number and is also divisible by 5.
The answer is 585.

I'm begging someone please help pleasedeeeeeeeeeeeeee PLEASEEWW SOMEONE I REALLY NEED HELPPP PLEASEEEEEEE

artcher [175]

Answer:

2 oldies and 6 new releases

Step-by-step explanation:

let x equal number of oldies

let y equal number of new releases

2x + 4y = 28

x + y = 8

x = 8 - y

2(8 - y) + 4y = 28

16 - 2y + 4y = 28

2y = 28 - 16

2y = 12

y = 12/2

y = 6

x = 8 - y

x = 8 - 6

x = 2

Solve for x in the equation x² - 4x - 9 = 29.

alexandr1967 [171]

Answer: First option.

Step-by-step explanation:

1. To solve this problem you can applly the quadratic formula, which is shown below:

$x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}$

2. The quadratic equation is:

$x^{2}-4x-9-29=0\\x^{2}-4x-38=0$

3. Then:

a=1

b=-4

c=-38

4. Therefore, when you substitute these values into the quadratic formula, you obtain the following result:

$x=\frac{-(-4)+/-\sqrt{(-4)^{2}-4(1)(-38)}}{2(1)}$

x=2±√42
