Answer:
Step-by-step explanation:
The answer to this question is A. 3
Step-by-step explanation:
I don't understand, why there is this segment about the 0 degrees Kelvin.
any material, water or the glass the water is in, or the air, or the floor or the wall : the higher the temperature (the scale does not matter, as long both temperatures use the same), the more energy it contains (the faster the particles in that substance are moving/vibrating).
therefore a glass of water with 80 degrees will have much more energy than one with 20 degrees.
the same way an aluminum can (the actual name of that material is aluminium, but Americans seemingly cannot pronounce that) with 30 degrees has more energy than one with 20 degrees.
Answer:
20 + 3x ≥ 50
Step-by-step explanation:
After x days, John will have added 3x points to his total. The new total will be ...
20 +3x
We want that value to be at least 50, so we use the symbol "greater than or equal to" to express that relationship:
20 +3x ≥ 50

Brainly makes available a table of math symbols so you can choose the appropriate one to use in your expression. The number 2 is not the same as the symbol ≥. Using incorrect symbols makes it very difficult to tell what the intended problem is.
