Mathematics

11. We are trying to find the minimum amount of chocolate she needs.

12. The variable could be <em>any letter</em>, but we can use c. I think the label is lbs., but I'm not 100% sure.

13. The inequality is 8 + c ≥ 15, since the regular 8 and the addition should be greater than the minimum, 15.

14. Work: 8 + c ≥ 15 -> c ≥ 15 - 8 -> c ≥ 7

15. c ≥ 7 lbs.

Write an expression that can be used to find 4 x 275 using mental math and properties of numbers
julia-pushkina [17]
I would start by breaking apart the 275 into 200, 70, and 5. Then I would multiply 4 by each of those numbers, giving you 800, 280, and 20. Then, I would add those number back together (800+280+20) and that gives you a final answer of 1,100. 

The expression  that can be used would be...
4(200)+4(70)+4(5)

Are the ratios 2:1 and 19:10 equivalent?
Oduvanchick [21]

Answer:

No.

Step-by-step explanation:

2:1 and 19:10 are not equivalent.

Simply, because if you divide 9 by any number with the 10, it is not going to stay as a whole number. For example, 19 divided by 2 equals 9.5. 19 divided by 5 equals 3.8. So, no they are not equivalent.
