Take -5x + 3x = -2x

because there is a -3x and a 3x they cancel each other out.

and the -17 is left

-2x = -17

divide -2 by -17 = 8.5

-3x-3(-5x-17)=3
-3x+15x+51=3
12x=48
x=3

If y is equivalent to an equation you can substitute that equation in for the y variable in the other equation bc they have the same value. Which it what I did.

Find the slope of the line that passes through the pair of points (1/10,6) and (3/16,11/5)
Scrat [10]
The slope of a line is (change in y)/(change in x), so we can plug it in to here to get (11/5-6)/(3/16-1/10). It doesn't matter which y value you subtract from, but just make sure that the number you subtract from in both the numerator and denominator is from the same point!

$12.95 for 3 pounds of nuts or $21.45 for 5 pounds of nuts
Zarrin [17]

First, find the base rate of both of the numerals, to do this simply divide the price by the number of units.

12.95 divided by 3 is 4.32 ( rounded to nearest cent )

21.45 divided by 5 is 4.29 ( rounded to nearest cent )

So, if you want the better deal ( which is what I've interpreted ), then 5 pounds of nuts is the better deal <u>BY</u> 3 cents.

Hope this helps, if not, comment below please!!!!
