Answer:
x = 40
m∠Q = 105°
m∠R = 40°
m∠P = 35°
Step-by-step explanation:
Sum of Angles in a Triangle: 180°
Step 1: Define variables
m∠Q = 2x + 25
m∠R = x
m∠P = x - 5
Step 2: Set up equation
m∠Q + m∠R + m∠P = 180°
2x + 25 + x + x - 5 = 180°
Step 3: Solve for <em>x</em>
4x + 20 = 180
4x = 160
x = 40
Step 4: Solve for measure angles.
m∠Q = 2x + 25
m∠Q = 2(40) + 25 = 80 + 25 = 105°
m∠R = x
m∠R = 40°
m∠P = x - 5
m∠P = 40 - 5 = 35°

Step-by-step explanation:
1. you can write an equation to represent the word problem
20-(2.10+0.9x)
20-(2.10+0.9(13)
20-(2.10+11.7)
20-(13.8)
6.2
Answer:
16
Step-by-step explanation:
186 / 12 = 15.5 round that up and you get 16
Answer:
Step-by-step explanation:
A new car is purchased for $25,000 over time its value depreciates by one half every 5 years. How long, to the nearest tenth of a year, would it take for the value of the car to be $5,000?
The formula now given as:
F = P(1 - r) ^t
F = Future value = $5000
P = Present value = $25000
r = Depreciation rate = 1/2 every 5 years
Hence:
5000 = 25000( 1 - ) ^t
