In London today, four times the high temperature was more than twice the high temperature plus
4vir4ik [10]

Answer:

Let's define the high temperature as T.

We know that:

"four times T, was more than 2*T plus 66°C"

(i assume that the temperature is in °C)

We can write this inequality as:

4*T > 2*T + 66°C

Now we just need to solve this for T.

subtracting 2*T in both sides, we get:

4*T - 2*T > 2*T + 66°C - 2*T

2*T > 66°C

Now we can divide both sides by 2:

2*T/2 > 66°C/2

T > 33°C

So T was larger than 33°C

Notice that T = 33°C is not a solution of the inequality, then we should use the symbol ( for the set notation.

Then the range of possible temperatures is:

(33°C, ...)

Where we do not have an upper limit, so we could write this as:

(33°C, ∞°C)

(ignoring the fact that ∞°C is something impossible because it means infinite energy, but for the given problem it works)

Determine which postulate or theorem can be used to prove that<br> REM= DME.
Snowcat [4.5K]

Answer:

SSS

Step-by-step explanation:

REM and DME share a side. This side is of course congruent.

In addition, sides RM and ED are marked as congruent, as are RE and MD.

All three corresponding sides of each triangle are congruent, which proves the triangles' congruency.

No information is given about the angles in these triangles, so none of the other theorem answer choices are valid.

Please mark brainliest! :)
