Finding the Value of 16-9: Which Pair Of Equations Show You How To Find 16-9
To find the value of 16-9, we can use two equations: 1. 16 = 4x + 8 2. 9 = 2x + 1
Simplifying the Equations, Which pair of equations show you how to find 16-9
We can simplify the first equation by subtracting 8 from both sides:
- 16
- 8 = 4x + 8
- 8
- = 4x
x = 2
We can simplify the second equation by subtracting 1 from both sides:
- 9
- 1 = 2x + 1
- 1
- = 2x
x = 4
Examples of Solving the Equations
To solve the first equation for 16-9, we substitute x = 2 into the equation:
- = 4(2) + 8
- = 8 + 8
- = 16
To solve the second equation for 16-9, we substitute x = 4 into the equation:
- = 2(4) + 1
- = 8 + 1
- = 9
Applications of the Equations
These equations can be used in various real-world scenarios, such as:
- Calculating the area of a rectangle with a length of 16 units and a width of 9 units: Area = length × width = 16 × 9 = 144 square units
- Finding the ratio of two numbers: 16:9 = 16/9 ≈ 1.78:1
