Answer: $18.51
Step-by-step explanation:
She paid $50
Her total purchases
$9.99 + $21.50 = 31.49
Change = (50 - 31.49) = 18.51
Answer:

Step-by-step explanation:

Answer:
z = 106, y = 23
Step-by-step explanation:
z and 74 is a supplementary angle which is equal to 180 degrees.
z + 74 = 180
z = 106
5y - 9 and z is a vertical angle, so the are equal to
each other.
5y - 9 = z
5y - 9 = 106
5y = 115
y = 23
The first thing we must know is the following definition:
d = v * t
Where,
d: distance
v: speed
t: time
Therefore, the total distance traveled in this case is:
(5.5) * (0.5) + (1.5) * p = 13.25
Rewriting:
2.75 + 1.5p = 13.25
Clearing the value of p we have:
p = (13.25-2.75) / (1.5)
p = 7
Answer:
an equation representing this situation is:
2.75 + 1.5p = 13.25
