I think we need more information on what topic you are on in algebra at the moment. But my best guess would be to solve for x, and then place your answers on the x-axis. This would be questionable though, because you would get many 0=(some number), which would be answered as untrue. Question numbers 4, 6, and 9 would all be untrue. Other than that,
1) x = 1
2) x = -2
3) x = 0
4) 0 = -3 (untrue)
5) x = -1
6) 0 = -8 (untrue)
7) x = -3/2
8) x = 0
9) 0 = -1 (untrue)

There are 53 cans of tomato sauce on
the shelf, 24 cans of tomato paste and
16 cans of crush tomatoes.
What is the ratio of cans of tomato
sauce to crushed tomatoes?
What is the ratio of crushed tomatoes
to tomato paste?

Answers

53:16 and 16:24 for the second part
to find the ratio of cans of tomato sauce to crushed tomatoes, you just need to put the numbers of each together and put the word “to” in between the numbers or just add a colon (:). the number of cans of tomato sauce is 53, and the number of crushed tomatoes is 16, so the ratio is 53:16. The same goes for the next question. The number of crushed tomatoes is 16 cans, and the number of tomato paste is 24 cans. Since the ratio is the two numbers compared, the ratio is 16:24. Hope this helped!

Bella wants to buy a new laptop because hers broke. Best Buy is having a double discount sale. The computer originally costs $830 and there is a 40% discount and then another 40% discount. How much will Bella pay for the laptop

Answers

answer: $298.80

there’s 2 ways to do this:
1. First Discount:
40% of 830 = .40 * 830= 332
830 - 332 = 498
Second Discount:
40% of 498 = .40 * 498 = 199.20
498 - 199.20 = 298.80

2. First Discount
100-40 = 60% (you’re paying 60% of the price)
60% * 830 = .60 * 830 = 498
Second Discount
60% * 498 = .60 * 498 = 298.80
^you’re paying 60% of discounted price
