5x +4y=23
-5(x-4y=-5)

5x+4y=23
+(-5x+20y=25)

24y=48
y=2

Now plug y value into one of the equations and solve for x

X-4(2)=-5
X-8=-5
X=3

So the answer is (3,2)

How do you find the median of these numbers $17.49, $11.29, $16.89, $11.79?
luda_lava [24]
Good morning, kid. It's quite easy.

The median is the middle number in a set after you place them least to greatest:

$11.29, $11.79, $16.89, $17.49

Well, since the numbers in the set are even, meaning there are only 4 numbers, we pick out the 2 middle numbers which would be, $11.79 and $16.89. Find the average (add them and divide by 2) and you'll get the median.

$11.79 + $16.89 = $28.68/2 = $14.34
Thus, the median is: $14.34
