22. Your class hopes to collect at least 325 cans of food for the annual food drive. There were 135 cans donated the first week and 89 more the second week.
a. Write an inequality that describes this situation. Let c represent the number of cans of food that must be collected by the end of the third week for your class to meet or surpass your goal.
b. How many cans are needed to meet or surpass your goal?
a.) 135 + 89 + C ≥ 325
224 + C ≥ 325
b.) 224 + C ≥ 325
C ≥ 325 - 224
C ≥ 10

So 2011 is before 2016
c+135+89>325
c>325-89-135

Just use Mathway to get most of the answers.
This quiz is for Nevada Connections Academy. I'm not certain if this quiz is identical. <= equals less than or equal to >= equals greater than or equal to
1. 11 D
2. 4 B
3. 2 A
4. {1, 2, 4, 8, 16} A
5. {2, 4, 6, 8} A
6. x >=-2 A
7. 2.25k >= 180, k>=80 D
8. 80 <= 82+88+n/3 <=85;70<=n<=85 A
9. 2.3 sec and 5 sec A
10. {3, 9, 15} A
11. {cola, root beer, lime, lemon, orange, cherry} D
12. 220 B
13. x >= 3 A
14. 0 with a slash, {-3}, {6}, {-3, 6} B
15. y < =-3 D
16. z > 9/20 D
17. y > 2/15 C
18. y <= -2 B
19. z >= -20 D
20. y >= -6 C
21. y <-5 or y >2 A
22. x <= -10 or x >=2 A
23. Solve yourself
I may have gotten one of the letters wrong so double check the answers are right.
I just did the test (I'm not in the northern California connexus I'm in Indiana) and 2Kool4Skool was pretty much correct, with a few exceptions.
My answers are:
1)c
2)b
3)a
4)a
5)d
6)d
7)d
8)d
9)c
10)d
11)a
12)a
13)b
14)b
15)d
16)c
17)c
18)a
19)d
20)c
21)d
22)a
23) same as 2Kool4Skool
Hope this helps, and use it wisely ^~^
