Answer:
Amount owed = 4.5x - 15
Step-by-step explanation:
x sandwiches will cost:
$4.50x
She has $15
She has to pay:
$(4.5x - 15) more
the money that Shelly will owe after buying x sandwiches and using the card will be:
if x < 4 then 15 - 4.5x <= 15 - 3*4.5 = 1.5 she will not owe anything plus she will receive change of $1.5.
if x=> 4 then 4.5x - 15 => 18 - 15 = 3 that is Shelly will owe 4.5x - 15 dollars.
x≥40 is the answer to your problem
0 is the answer
48
The triangle was only rotated. The size did not change, so the corresponding angles would remain identical.
Because C is 28 degrees C' would also be 28 degrees.
