Answer:

Step-by-step explanation:
We are given the following in the question:
Let the equation:

be the linear equation that represent temperature at an elevation x.
Temperature at 6000-foot level = 76 f

Temperature at 12000-foot level = 49 f

Solving the two equation, we get,

Thus, we can write the linear equation as:

Answer:
its 6900000
Step-by-step explanation:
6hue and 388
Answer:
Step-by-step explanation:
47x+12y
The values of the number is 43
x+21=64
subtract 21 on each side
x = 43
7a-2b = 5a + b
2a=3b
a = 3b/2
