Answer:
The equation for a is 
The altitute is 101,428.57 feet
Step-by-step explanation:
You know that the relationship between ground temperature and atmospheric  temperature can be described by the formula 
t = -0.0035a +g
where:
- t is the atmospheric  temperature in degrees Fahrenheit
- a is the altitude, in feet, at which the atmospheric temperature is  measured 
- g is the ground temperature in degrees Fahrenheit. 
Solving the equation for a: 
-0.0035a +g=t
-0.0035a= t - g


<u><em>The equation for a is </em></u> <u><em></em></u>
<u><em></em></u>
If the atmospheric temperature is -305 °F and the ground temperature is 50 °F, then t= -305 °F and g= 50 °F
Replacing in the equation for a you get:


a= 101,428.57
<u><em>The altitute is 101,428.57 feet</em></u>
 
        
             
        
        
        
Answer:
X+Y=26
X-Y=12
Step-by-step explanation:
fiction books= X
non fiction books= Y
then, 
fiction books= X 
non fiction books = X-12
but Y= X - 12 
from. the statement,
X+Y = 26
X-Y=12
