Given:
The equation
Answer:
Step-by-step explanation:
To simplify the given expression, we use the Laws of Exponents; that is, when the bases are the same in two sides of the equation, the exponents can be equated.
So, we begin by expressing 625 on the right hand side as a power of 5 which is the same base as on the left hand side.
Then, we equate the exponents and simplify for x as we usually do.
The following is the solution.
We know
and
So,
We now equate the exponents on both sides as solve for x like we would normally do
Correct answer is Option A: 18/48 = 21/56
You’ll have to divide the numerator by the denominator of each fraction to see whether they have the same quotient:
18/48 = 0.375
21/56 = 0.375
The other options are not proportional.
B) 20/28 = 15/18:
20/28 = 0.714
15/18 = 0.833
Thus, 20/28 ≠ 15/18
C). 3/5 = 13/10
3/5 = 0.6
13/10 = 1.3
Hence, 3/5 ≠ 13/10
D) 7/10 = 10/7
7/10 = 0.7
10/7 = 1.43
Thus, 7/10 ≠ 10/7
These solutions prove that the correct answer is A) 18/48 = 21/56

I am assuming when you write 27x5 u mean "27 times x to the power of 5".
therefore, your answer is 9x3-11x2-7x
Answer:
✖ both sides
Step-by-step explanation:
you take both numbers and you multiply it
Answer:
2.75
Step-by-step explanation:
first convert it to a improper fraction
2 3/4 = 11/4
then dividing the numerator by the denominator.
11/4 = 2.75
hope this helped!
