Step-by-step explanation :
As we are given the following expression:
where,
P = total price (in dollars)
n = number of balls used
Given:
n = number of balls used = 10
Now we have to determine the cost of 10 balls.
Thus, the cost of 10 balls will be, 13.5 dollars
Answer:
B. x = 15, m∠Q = 75°
Step-by-step explanation:
Given:
m∠P = 105°
m∠Q =
Angles P and Q are supplementary angles
To find value of and m∠Q.
Solution:
[Sum of supplementary angles =180°]
[Substitution ∵ m∠P = 105° and m∠Q =
]
Subtracting both sides by 105°.
Dividing both sides by 5.
∴
∴
