16/3 of alternative forms are 5 1/3 or 5.3
Answer:
1/19( -171 - 10√5 + 40√30)
Step-by-step explanation:
Probably the best way to do this would be to mutiply each fraction ( top and bottom) by the conjugate of the denominator. This would then give a denominator with no radicals.
So 2√5 / √6 + 5 wil be multiplied by (5 - √6) / (5 - √6)) to give
(10√5 - 2√30)/ (25 - 6).
= 2√5 (5 - √6) / 19
Do the same with th other 2 fractions and the simplifuication will be a lot easier.
I did this and got 1/19( -171 - 10√5 + 40√30)

Answer:
shirt = $20
sweater = $35
Step-by-step explanation:
This question would be solved using simultaneous equation
Let the price of sweater be represented by a
Let the price of shirt be represented by b
The following equations can be derived from the question
2a + 4b = 150 equation 1
4a + 3b = 200 equation 2
Multiply equation 1 by 2
4a + 8b = 300 equation 3
Subtract equation 2 from 3
5b = 100
divide both sides of the equation by 5
b = 20
substitute for b in equation 1
2a + 4(20) = 150
2a + 80 = 150
collect like terms
2a = 150 - 80
2a = 70
divide both sides by 2
a = 35
Price of sweater = $35
Price of shirt = $20
It would be 48 cause one side is 8 and another is 6 multiple and the answer is 48
