Hello!

You solve this algebraically

4n - 9 = -9

Add 9 to both sides

4n = 0

Divide both sides by 4

n = 0

The answer is 0

Hope this helps!

The answer you are looking for is "n = 0".

This can be found by adding 9 to each side, which would leave you with "4n = 0". To get "n" by itself, you'd then divide both sides by 4. "N" in this case would equal 0, because 0 divided by any number, will always be 0.

To check this answer, you could replace "n" with 0, and solve the left side. This would leave you with "-9 = -9", meaning the answer is correct.

I hope this helps!

an item is regularly sold at $40. kala bought it at a discount of 35% off the regular price. how much did kala pay
KonstantinChe [14]

To solve this problem, we must first find the discount amount, and then subtract this amount from the total price of the item.

To find the discount amount, we must find 35% of $40. To do this, we must first convert 35% to its decimal equivalent by dividing 35/100. We do this because percentages are parts out of a total 100 percent, thus this fraction represents an equivalent value that we can multiply by other numbers. Using our knowledge that 35/100 = 0.35, we can now set up our expression:

35% of $40 (keep in mind that the word "of" refers to multiplication in math)

0.35 * 40

To solve, we just multiply these two numbers together, which gives us 14.

This means that Kala got a discount of $14 off of the original price of $40. To find out how much she paid for it, we must subtract $14 from $40, as modeled below:

$40 - $14 = $26

Therefore, Kala paid $26 for the item.

Hope this helps!
