Answer:
1001/1500
Step-by-step explanation:
The easiest method for doing this is to just average the two numbers.
e.g. to find a number x between the two numbers ab and cd
x=12[ab+cd]
=12[adbd+bcbd]
=ad+bc2bd
In this case…
x=(2×5)+(3×4)2×2×5=10+1230=2230=1115
You can easily see where that came from.
23=1015 and 45=1215
and the ‘common denominator’ means you just have to pick a value between 10 and 12 . i.e. 11
But you can also say…
23=100150 and 45=120150
and choose any of 101150,102150,...,119150
or
23=10001500 and 45=12001500
and choose any of 10011500,10021500,...,11991500
Factor the numerator and denominator then simplify.
6x^2 - 54 6(x^2 - 9) 6(x + 3)(x - 3) 6(x - 3)
-------------- = ------------- = ------------------ = ------------
5x^2 + 15x 5x(x + 3) 5x(x + 3) 5x
6(x - 3)
----------
5x
Answer:
I think it is the last one.
Apply radical rule
= (10^1/2)3/4x
Apply exponent rule: (a^b)^c = a^bc
= 10^1/2 . 3/4x
Simplify: 1/2 . 3/4x: 3x/8
= 10^3x/8
Answer:
$420 into the Bank of the US
Step-by-step explanation:
x + 4x + 5/4x = 2125
5x + 5/4x = 2125.
25x/4 = 2125
25x =8500
x = $340 into the 7/4 bank
4(340) = $1340 into the Catch Bank
1/4(1680)= $420 into the Bank of the US
