I need help finding 13-22

1 answer:

4 0

13. (3/8)*q + 12 = 36
3q/8 = 24
3q = 192
q = 64

14. 3 - (3/4)n = 9
-3n/4 = 6
-3n = 24
n = -8

15. (7/9)v + 2 = 23
7v/9 = 21
7v = 189
v = 27

16. 7 + (1/8)l = -2
l/8 = -9
l = -72

17. (v/-3) + 8 = 22
v/-3 = 14
v = -42

18. 8x - 16 + 8x = 16
16x = 32
x = 2

19. 12a - 14a = 8
-2a = 8
a = -4

20. 7c - 8 - 2c = 17
5c = 25
c = 5

21. 6 = -y + 42 - 2y
-36 = -3y
y = 12

22. 16 + 8r - 4r + 4 = 24
20 + 4r = 24
4r = 4
r = 1

Answer:

e. no solution

Step-by-step explanation:

You would be looking for factors of +5 that have a sum of -4. There are none (no solution). None of the values offered in the answer choices have a product of +5.

The discriminant of the quadratic is (-4)² -4(1)(5) = -4, so the roots are complex.
