Answer 4

Distribute the -1/2

Answer 5

could you show me step?

Answer 6

The first step is to distribute the -1/2 to each term inside the ( ).

Answer 7

i got 4/8

Answer 8

my friend got 4-2+1/4

Answer 9

Apply the distributive rule:

a(b + c) = ab + ac

Answer 10

hero, its not (a+b) tho.

Answer 11

what is c in my case?

Answer 12

@Dodo1 : @Hero is correct - a is -1/2; b is 4; c is -1/2(qw).

Answer 13

could you show me step?

Answer 14

i got 2+1/4

Answer 15

4−0.5(4−0.5qw) = 4-2+0.25qw = 2+0.25qw

So you are almost correct; you forgot to include the 'qw' though.

Answer 16

@Dodo1: You'd also need to check if this question has an equation, e.g. the previous question=0. In which case, you can solve for qw.

Answer 17

i see so you just use decimals rather than function

Answer 18

Yes, but you can use fractions - I'm using decimals so I don't need to use the Equation editor here in Open Study.

Answer 19

how did you get 2?

Answer 20

i got it

Answer 21

Ok, the answer's the same as yours, with the exception of the 'qw' which you omitted in your answer.
