Question

Which phrase could be represented by this expression?

d/2 – 5


A.
twice a number decreased by five

B.
half a number less than five

C.
five less than twice a number

D.
five less than half a number

Answer 1

So.. let's say "d" is the number...
We want to know what this expression could mean:
d/2 - 5

You want to note that d/2 ALSO can be written as 1/2 * d
we said d = number.. therefore
1/2 *d - 5 would mean...?

Answer 2

im guessing it would be b ._.

Answer 3

not really understamding here... :(

Answer 4

you're closeee but not quite there :)
When we say:
half a number LESS than 5.. this would mean:
5 - 1/2d (where "d" is the number")

We want it the other way around right?
1/2d - 5
So this would mean 5 less than half a number

Answer 5

wait it's D i believe :(

Answer 6
