Question

Which expression is equivalent to

7/2h-3(5h-1/2)? Explain

A) -23/2h+3/2

B) -23/2h-3/2

C) 37/2h+3/2

D)37/2h-3/2

Answer 1

the answer to the question is b

Answer 2

The given expression is

`(7)/(2)h-3(5h- (1)/(2))`

First we have to distribute -3 on 5h and -1/2

That is,

`=(7)/(2)h-15h+ (3)/(2)`

Now we have to combine the like terms, that is

`= (7h-30h)/(2) + (3)/(2) = - (23h)/(2) + (3)/(2)`

So out of the given four options, correct option is A .
