The answer is now!
2x+6 < 5(x-3) distribute 5 into x-3 2x+6 < 5x-15 move all x to one side 6 < 5x-15-2x simplify 6 < 3x-15 move 15 to other side 6+15 < 3x simplify 21 < 3x get x alone by dividing 3 on both sides 21/3 < 3x/3 simplify 7 < x and that's how you solve it.
well you can always just plug the answers into both equations and solve them. Answer: A
protons and neutrons. The electrons are on the outside keeping the protons inside.

Well you know the force and mass. So use this formula: F=ma. F=250N m=20kg Just rearrange it and you will be able to get the maximum acceleration the sack can withstand before breaking.
yellow, blue, and red.
Well lets break this up first. Clue 1: is i am a 3 digit number less than 200, only number possible there is 1. Clue 2: is the tens is 2x ones' place. so look at clue 3. clue 3: The ones place is 2. So then the tens is 2 times 2 which is 4. So the number
