Divide both sides by 2

x= 18

I hope that's help :)


another way you can do that is to divide 36 by 2 and it will be 18


I hope that's help and if you have questions please ask ;)

$450+4%=$???????????????

Answers

In order to solve this, we first need to convert the percentage into a decimal. We can do this by either multiplying the percentage by 100, or (my personal shortcut) just moving the decimal point over two places to the left.

4% = 0.04

Now, we need to multiply the decimal by the amount of money we have.

450 * 0.04 = 18

Now, we need to add this newfound amount to the total, since we are adding the 4%

450 + 18 = 468

$450 + 4% = $468
Hope that helped =)

y+9=1/5x menjadi y= 1/5x -9

N divided by 5 plus negative 6 equals 9. whats n?

Answers

So,

(n)/(5) + -6 = 9
(n)/(5) - 6 = 9

Add 6 to both sides
(n)/(5) = 15

Multiply both sides by 5
n = 75

Check
(75)/(5) - 6 = 9
15 - 6 = 9
9 = 9\ This\ checks.

S = {75}
n/5 -6 = 9 simplifies to n/5 = 15 then you can cross multiply and that comes out to 75 so n = 75
