3 - x = -16/2
3 - x = -8
-x = -8 - 3
-x = - 11
x = 11</span>
Answer:
9/4
Step-by-step explanation:
2 1/4 = 9/4 From mixed fraction to an improper fraction: "the numerator of the improper fraction" = "denominator" xx "the whole number" + "the numerator of the mixed fraction" The denominator remains as it is. So 2 1/4 = (4 xx 2 + 1)/4 = 9/4
Answer:
Step-by-step explanation:
Yes!
The square root of a number represents the "middle number" possible as a divisor of any given number.
All other factors will have one number above the square root and one number below the square root.
For example consider 80.
The prime factors are 2 * 2 * 2 * 2 * 5. The square root of 80 is about 9, so any factor of 80 must have all the primes under the square root or 1 above and 1 below.
10 * 8 is one such pair. 10 is above 9 and 8 is below it.
=============
I have read the comments made by others. I believe what they are saying is true, but I'm not interpreting the question the same way. I'm looking at these as pairs. The commenter is taking 1 prime at a time. It's a fair way to look at the question. You have to decide how you want to present your answer. You could go either way. That's the problem with some of these questions.

Answer:
The percentage decrease in TV price after five years is 6.89
Step-by-step explanation:
Given as :
The cost of TV five years ago = $ 2400
The present cost of TV = $ 1680
Let The decrease percentage in five years = x
So, The cost of TV after T year = Present cost × 
Or, $ 1680 = $ 2400 × 
Or, 0.7 =
Or, 
= 1 - 
Or, 0.9311 = 1 -
Or, = 1 - 0.9311
∴, = 0.0689
I.e x = 0.0689 × 100 = 6.89
Hence The percentage decrease in TV price after five years is 6.89 Answer
