Answer:
The fundamental counting principle is the primary rule for calculating the number of possible outcomes. If there are p possibilities for one event and q possibilities for a second event, then the number of possibilities for both events is p x q.
54+20=74
74*2=148
I believe the backpack cost $148. Hope this helps :)
For this case we must simplify the following expression:
We solve the parenthesis:
We apply distributive property to the terms within parentheses:
We add similar terms:

Answer:
m=-3
Step-by-step explanation:
Answer:
∠A = 90
∠B = 30
∠C = 60
Step-by-step explanation:
Let ∠B = x
∠A = 3x
∠C = x + 30
Angle sum property of triangle: Sum of three angles of triangle is 180
x + 3x + x + 30 = 180 {Combine like terms}
5x + 30 = 180
5x = 180 - 30
5x = 150
x = 130/5
x = 30
∠A = 3*30 = 90
∠C = 30 + 30 = 60
