Since (x - 2)° and (2x + 5)° represent a pair of supplementary angles, then their sum must be equal to 180°. Therefore, the two supplementary angles are 57° and 123°.

which inequality represents the following situation 3/5 times 5 less than a number is no more than 27

andrey2020 [161]

The answer is $\frac{3}{5}(x-5) \leq 27$

Let's build the expression piece by piece, translating sentences into formulas:

"3/5 times..." $\to \frac{3}{5} \times \ldots$

"5 less than a number..." $\to x-5 \ldots$

So, the first block becomes

"3/5 times 5 less than a number..." $\to \frac{3}{5}(x-5) \ldots$

"...is no more than 27" $\ldots \leq 27$

So, putting the pieces together, you have the answer
