AnswThe method is to separate the variable from everything else. That means getting the variable on one side of the equals sign and everything else on the other side. A=5B+8.
Subtract 8 from each side: A-8=5B.
Now divide each side by 5: (A-8)/5=B.
So B=(A-8)/5.

Step-by-step explanation:
Answer:
The train ride is 3.5 hours
Step-by-step explanation:
We know that distance is equal to rate times time
d = rt
We know the distance and the rate
420 = 120*t
Divide each side by 120
420/120 = 120t/120
3.5 =t
The train ride is 3.5 hours
To find the unit rate you do distance ÷ time
16 miles ÷ 2 hours = 18
To find the time you do distance ÷ unit rate
20 miles ÷ 18 = 1.1
To find the distance you do time • unit rate
3 hours • 18 = 54
2) 1.1, 54, 1.8, 90, 27
3) 48, 3, 30, 2, 1
A ) The angle formed by 2 consecutive radii:
Ф= 360° : 8 = 45°
b ) The angle formed by a radius and a side of a polygon:
α = (180° - 45°): 2 = 135° : 2 = 67.5°
Answer:
B ) 45°, 67.5°
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
time of day of watering plants vs growth rates
Step 02:
method of collecting data:
we must analyze the options to find the solution.
sample survey ===> FALSE
observational study ===> observes individuals and measures variables of interest but does not attempt to influence the responses. TRUE.
experiment ===> FALSE
The answer is:
observational study
