Step-by-step explanation:
Answer:
You wrote:
2*x + 4 = 14
This is not an inequality, so i guess that you wanted to write something like:
2*x + 4 ≥ 14
Now, this means that the left equation is always equal to or larger than 14.
Now, which type of problem this may represent?
Well, 2*x + 4 should represent something that is larger than 14, only that.
Then we can write something like:
"You have 4 dinosaur toys, and in the toy store near your house, they sell packs of 2 dinosaur toys. If you want to have at least 14 dinosaur toys, how many packs can you buy?"
Now x represents the number of packs that you buy.
2*x is the number of dinosaurs in these packs
2*x + 4 is the total number of dinosaurs that you have, when you also count the ones that you previously had.
2*x + 4 ≥ 14
Is the inequality that represents the problem.
Answer:
So, the probability is 1/6.
Step-by-step explanation:
There are 6 sides on a dice because you got 2 each of the three times.
