Answer:
A
Step-by-step explanation:
The easiest way to figure this out is to substitute in the variables. So for a, 2=-5+7 is correct, and 7=0+7 is correct as well. If you were to look at the other answers, you would see that the equation would not match up. Hope this helps!
<h2><u>Given</u> :</h2>
The given equations are :


Let's solve for g in equation (2) :


now, let's plug value of g from equation (3) into equation (1) :





plugging value of b in equation (3) :



since " g " represents ground seats, number of ground seats :
=》396
And " b " represents balcony seat, therefore it is equal to :
=》312

Answer:
converts Celsius to Fahrenheit.
converts Fahrenheit to Celsius.
Step-by-step explanation:
Write given data in the table

Let the expression for the function be

Note, that this equation is linear equation and it is well-known fact that the Celsius to Fahrenheit dependence is linear.
Substitute corresponding values into this expression:

Subtract these two equations:

Substitute it into the first equation:

So,

This is the function which converts Celsius to Fahrenheit.
And function
converts Fahrenheit to Celsius.
