Lorenzo found the total surface area
Answer: choice B is true.
Step-by-step explanation:
We are asked to find which value is similar to the value of the expression:
30% of 81.
We know that 30% of 81 could also be represented mathematically as:
30%×81=
which could also be written as:
choice A:
=
Which is not similar to equation (1).
Hence choice A is not similar.
Choice B:
This expression is similar to equation (1).
Hence choice B is true.
Choice C:
Which is not similar to equation (1).
Hence, choice C is not true.
Choice D:
=
Which is not similar to equation (1).
Hence, choice D is not true.
Choice E:
Which is not similar to equation (1).
choice D is not true.
Answer:
Step-by-step explanation:
The key to answering this is to know that the only time you'll change the direction of the sign is when you multiply or divide by a negative number.
-46 - 8x > 22
-8x > 22 + 46
-8x > 68
x < 68/-8 (we divided by -8 so the inequality changed direction)
x < -17/2
