Answer: R x 4 - 6
Step-by-step explanation:
Answer:
20 ≤ x ≤ 70
Step-by-step explanation:
Given that:
30 ≤ x + 10 ≤ 80
By solving the left half inequality first:
30 ≤ x + 10
Subtracting 10 from both sides:
30 - 10 ≤ x + 10 -10
20 ≤ x
Now solving inequality of right half:
x + 10 ≤ 80
Subtracting 10 from both sides:
x + 10 -10 ≤ 80 - 10
x ≤ 70
So after simplification we get:
20 ≤ x ≤ 70

Answer:
-1/32
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
1. a = 18, 2. n = -19, 3. x = -17, 4. v = -6, 5. a = 9, 6. x = -2, 7. k = -4, 8. m = -19
9. n = 3, 10. a = -7, 11. n = -5, 12. n = -6, 13. x = -1/3, 14. m = 2/3 15. m = -9.8
16. n = 7.9, 17. x = 0, 18. b = 2, 19. v = -8, 20. b = -4, 21. n = 3, 22. p = 3.3
You would need to add 360L of the 20% ethanol solution.
