Step-by-step explanation:
5x + 8 = x - 9
5x - x = - 9 - 8
4x = - 17
x = - 4 1/4
Can you explain the other stuff you wrote down so I can help? Can you put the stuff on a line so I can understand?
Answer:
Tom has 70 cards, and Harry has 28 cards.
Step-by-step explanation:
Let h = number of cards Harry has.
Then the number of cards Tom has is 2 1/2 * h = 2.5h.
Together they have 2.5h + h = 3.5h number of cards.
Together they have 98 cards.
3.5h = 98
h = 98/3.5
h = 28
Harry has 28 cards.
Tom has 2.5h = 2.5 * 28 = 70
Answer: Tom has 70 cards, and Harry has 28 cards.

Step-by-step explanation:
I havent really done this in a while but I started by making the line into a right triangle and counted how many boxes were inside(6 on the bottom 4 on the side). Then I used the Pythagorean theorem (which is the process of taking the sides and making them squares) < To simplify that explanation (I squared the sides(6 and 4).) so now we are left with 6² + 4² = x². next what you do is simplify your terms. (6² = 36, 4² = 24. 36 + 24 = 60) We have 60 = x² but we aren't don't yet, now we have to remove the square from x. and to do that we have to square root 60 and x² ( squared numbers being square rooted just leaves the regular number.) when square rooting 60 you are left with 7.8≈.
I hope this helps you, like i said its been a while since ive done this.
