Answer:
10 minutes
Step-by-step explanation:
Let's call the Acme Company A and Beltone as B
Let m be the number of minutes
A = $21 + $0.05m
B = $15 + $0.11m
- A = B
- $21 + $0.05m = $15 + $0.11m
- $6 + $0.05m = $0.11m
- $6 = $0.06m
- 10 = m
It will take 10 minutes for both prices to be equal.

You have to organize the parameters of the real-world situation that is known and unknown. Also, you have to distinguish which of them are dependent and independent. Next, you assign letters as your variables. Lastly, you make an algebraic expression by translating the relationship into the mathematics.

Step-by-step explanation:
Given that the rectangle has a height = 2, and width of 
Area of the whole rectangle can be calculated as:
Use the distributive property of multiplication by using 2 to multiply each term in the expression, 
Answer:
x = 32, ∠A = 132
Step-by-step explanation:
A and B are equal. Set both equations equal to each other.
5x - 18 = 3x + 42
Add 18 to both sides and subtract 3x from both sides.
2x = 60
Divide both sides by 2.
x = 30
Now plug x back in to solve for angle A.
5(30) - 18 = 132
