Answer:
4x+7y
4(3/4) +7(-1/3)
3-7/3
=2/3
please mark as brainliest
It is C) 2.55 because i was taught that you can subtract the negative from the positive. 5.35-2.8=2.55 and it is positive
4 was rolled 2 times
5 also 2 times
6 was rolled 4 times
So the result was greater than three eight times out of 12 rolls.
P=8/12=2/3
For this case we must resolve the following inequality:

Subtracting 7 from both sides of the inequality we have:

Dividing by 3 to both sides of the inequality we have:

We multiply by -1 on both sides, taking into account that the sense of inequality changes:

Thus, it is observed that to solve the inequality it is necessary to change the meaning of it.
ANswer:
False. It is necessary to change the sense of inequality
