Confused on what "<=" means...

7.28 + 8.06 = 15.34

15.34 - 1.58 = 13.76

13.76 / 4 = 3.44

70p + 92n = 86(n + p)

70p + 92n = 86n + 86p

16p = 6n

p/n = 6/16 = 3/8

(x + y)^2 = 45

x^2 + y^2 + 2xy = 45

x^2 + y^2 + 2(8) = 45

x^2 + y^2 = 29

(x-y)^2 = x^2 + y^2 -2xy

[x^2 + y^2] - 2xy =

[29] -16 = 13

Find the linear equation of the blue and orange lines:

orange: y > x - 2

blue: y < -1/2x + 2

Then change these equations into the ones above:

y  >  x - 2

2y + x < 4

t + 46 = (2t - 14) + (3t - 37) 

t + 46 = 5t - 51

4t = 97

t = 97/4 = 24.25

(3x + 10) = (2x + 15)

x = 5

2(5) + 15 = 25

2(90-x) = (180-x)-23

180 - 2x = 180 - x - 23

x = 23

Maybe a typo from the guest asking...

4610 + 6810 = 11420
