Andre sells T-shirts. He charges customers $19 per T-shirt, plus a delivery
fee of $8 per order. The amount, y, that
Andre charges for an order of x T-shirts is
represented by the equation y = 19x + 8. A
customer paid $217 for an order of
T-shirts. How many T-shirts did the
customer order?

11

Step-by-step explanation:

217 = 19x + 8

209 = 19x

x = 209/19

x = 11

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
