Which expression is equivalent to the given expression?
15(12-x)
A.
hope this help
Answer:
x ≤ 30
Step-by-step explanation:
'at most' means the same as 'less than or equal to'.
The sign 'for less than or equal' to is ≤.
So it's simply x ≤ 30.
Answer:
For the one including 4w the answer is - 7
The one with n/2 is - 12
Step-by-step explanation:
4w=-13-15
4w=-28
w=-7
Multiply by 2 on both sides
-24=n-12
-24+12=n
Always write it in the variables perspective.
n=-12
Assuming that each kind of seat is unnique and different from each other
( assume 4 kinds, premium, gold, silver, bronze, or premium, not premium, not premium, not premium)
so fraciton is parts out of whole so
1 out of 4 toal parts is 1/4
After you realize that
0.00025 = 2.5·10^-4
= 250·10^-6 or 250 μ
= 250,000·10^-9 or 250,000 n
then it becomes a matter of semantics. Both A and D are correct representations, so choice B is incorrect.
Choice C present a dilemma. If you say it is correct, then there are 3 correct choices (A, C, D), not two, so C is incorrect.
If you say it is incorrect, then there are two correct answers (A, D), making choice C correct.
I'd probably choose C and try to avoid the argument with my teacher.
