d+s ˃ -3 d˃-7
find s
the answer supposed to be 4, but I think it is not correct, because depending on d it might be pretty much anything.. any thoughts?
well,
-3d>-7
3d<7
d<7/3
s>-4d>-4(7/3)
I left spaces but did not show, sorry..
d+s ˃ -3
d˃-7
find s
To find the value of s given d+s > -3 and d > -7, we can use deductive reasoning.
First, let's combine the inequalities:
d + s > -3
d > -7
To isolate the variable s, we can rearrange the first inequality:
s > -3 - d
Next, we can substitute the second inequality into the expression for s:
s > -3 - (-7)
s > -3 + 7
s > 4
From this, we can conclude that s must be greater than 4. Therefore, the answer of s = 4 is not correct.
In fact, as you correctly pointed out, the value of s can vary depending on the value of d. We cannot determine an exact value for s without knowing the specific value of d.
