Answer:
|a-c| meters
Step-by-step explanation:
If I am piloting an airplane to prepare for landing, I change the plane's altitude from a meters to c meters, then the expression that represents the distance between two altitudes is given by |a-c| meters, not by |a+c|.
For, example if the altitude of the plane changes from 1000 meters to 500 meters for preparing for landing then the distance between those two altitudes is |1000 - 500| = 500 meters. (Answer)
But using the expression |a+c|, I will get the wrong answer as |1000 + 500| = 1500 meters.

Step-by-step explanation:
Given that Sam is an artist, and he wants to purchase frames to display his work at home.
He wants to frame no fewer than 10 of his pieces, and he can spend a maximum of $225. Large frames cost $24, and medium frames cost $18.
<h3>To find the system of inequalities can Sam use to determine the number of large frames, x, and medium frames, y, that he can purchase to meet his needs :</h3>
Let x be the large frames cost
Therefore 
Let y be the medium frames cost
Therefore 
Sam's Spend amount is 
We can write the system of the given condition by


<h3>Therefore the option D)

and

is correct</h3>

Answer:
58
Step-by-step explanation:
1. let x be the unknown number
2. make an expression
x + 26/12 = 7/1
3. cross multiply
x +26 × 1 = x + 26
12 × 7 = 84
x + 26 = 84
4. move variables on one side and numbers on other side of the equal sign
x + 26 = 84
- 26 -26
x = 58
