Many people probably think that those who are good at math always do exact calculations, but estimation is actually a really useful tool, especially when it comes to things like percent discount. Suppose that you're shopping on a rack that offers off the lowest ticketed price, and you're interested in a sweater with a ticket price of .The sale price is what percent of the ticketed price?

well what you have to do is divide 84 by 6 so theanswer

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
