Answer:
a = (x - b)/2
Step-by-step explanation:
2a + b = x
-b -b
2a = x - b
/2 /2
a = (x - b)/2
for ex:
x = 3
b = 2
a = ((3) - (2))/2 = 0.5
a = 0.5
2a + b = x
2(0.5) + 2 = 3
Answer:
5.24 in
Step-by-step explanation:
The arc length is calculated as
arc = circumference × fraction of circle
= 2πr × 
= 2π × 5 × 
= 
≈ 5.24 in (2 dec. places )
Standard form of a linear equation is
Ax + By = C, where A, B, and C are integers.
Add 3 to both sides to get
4x + 4y = 3
6:45a to 7:45 = 1 hour
7:45 to 8:45 = 2 hours
8:45 to 9:45 = 3 hours
9:45 to 10:45 = 4 hours
10:45 to 11:45 = 5 hours
11:45 to 12:45 = 6 hours
12:45 to 1:45 = 7 hours
1:45 to 2:45 = 8 hours
2:45 to 3:00 = 8 hours and 15 minutes
then just add the 28 minutes to the 15 minutes
28 + 15 = 43
6:45a to 3:28p = 8 hours and 43 minutes.
Hope this helps.
