Answer:
For the mathematical system that consists of the set of real numbers together with the operations of addition, subtraction, multiplication, and division, the resulting properties are called the properties of real numbers.
Closure Property of Addition also holds in real numbers: The sum of two real numbers is a real number.
multiplication pairs any two real numbers with a real number to become a product a×b
for all real numbers a and b, the difference denoted as a - b is defined by: a - b = a + (-b).
Hence we can also apply the BODMAS rule to the real numbers.
Difference first do the work in the parenthesis and then subtract. Hoped it helped :3

Answer: Choice B) x = 1</h3>
================================================
Explanation:
The problem should read 6^(3-x) = 6^2. The 3-x must be in parenthesis to indicate that all of "3-x" is in the exponent and not just the 3.
Because both bases are 6, and because both sides are equal, this means that the exponents must be equal as well. Therefore 3-x = 2. Let's solve for x
3-x = 2
3-x+x = 2+x .... adding x to both sides
3 = 2+x
2+x = 3 ..... flipping both sides
x+2 = 3
x+2-2 = 3-2 .... subtracting 2 from both sides
<h3>x = 1</h3>
You can use logarithms to solve this problem, but the fact that the bases are both the same allows us to use this faster shortcut.
Answer:
C: $9.53*(0.86)
Step-by-step explanation:
To find Eric's lunch bill, we have to work backwards. Since Raj's bill is 14% higher, we have to make it 14% lower to get Eric's lunch bill. We can do this by multiplying the original price by 1-0.14.
$9.53*(1-0.14)=$9.53*(0.86)
