4 x - 9 y = 1
- 4 x + 6 y = - 2
- 3 y = - 1
y = 1
4 x - 9 y = 1
4 x - 9 ( 1) = 1
4 x - 9 = 1
4 x = 1 +9
4 x = 10
x = 10/4 = 2.5

Answer:
- $247,000,000 = 2.47 * 10⁸
- $5,200,000 = 5.2 * 10⁶
Step-by-step explanation:
Scientific notation allows us to write large numbers in smaller quantity by reducing the number to a figure less than 10 but more than one and then multiplying it by a power of 10 to show its actual size. For instance, 65,000,000 will be written as 6.5 * 10⁷ to represent the total number of digits that it has after the decimal.
$247,000,000:
This would be 2.47 * 10⁸
$5,200,000:
This is 5.2 * 10⁶.
