Answer:
36 degrees
Step-by-step explanation:
A+B=90
A-B=18
add these two equations:
2A = 108
A=54
B=36
We need to find the time taken to travel from Frederick, MD to Baltimore, MD at a speed of 15 miles per hour.
The time taken to travel the distance is 3 hours and 20 minutes.
The shortest route from Frederick to Baltimore is 50.2 miles via the I-70 E.
So we can assume this route will be taken.
Speed of the cyclist = 15 mph
Time is given by distance divided by speed.
So,
Converting to hours and minutes
The time taken by the cyclist would be about 3 hours and 20 minutes.

Answer:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
Step-by-step explanation:
First calculate the value of the 3 shirts as follows:
$ 71.83 - $ 7.99 = $ 63.84.
$ 63.84.
The general equation would be, where x is the value of shirt # 1, and the value of shirt # 2 and z is the value of shirt # 3:
x + y + z = 63.84, then for each shirt would be the following equations:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
For example, if we give values (always the sum of both under 63.84) to two shirts, x = $ 20, y = $ 30 then the value of shirt # 3 would be:
<em>z = 63.84 - 20 - 30 = $ 13.84</em>
Answer:
