Answer:
u = 3/4
Step-by-step explanation:
Solve for u:
-5 (6 - 4 u) - 6 u = 6 (u - 3) - 6
-5 (6 - 4 u) = 20 u - 30:
20 u - 30 - 6 u = 6 (u - 3) - 6
Grouping like terms, 20 u - 6 u - 30 = (20 u - 6 u) - 30:
(20 u - 6 u) - 30 = 6 (u - 3) - 6
20 u - 6 u = 14 u:
14 u - 30 = 6 (u - 3) - 6
6 (u - 3) = 6 u - 18:
14 u - 30 = 6 u - 18 - 6
Grouping like terms, 6 u - 18 - 6 = 6 u + (-18 - 6):
14 u - 30 = 6 u + (-18 - 6)
-18 - 6 = -24:
14 u - 30 = 6 u + -24
Subtract 6 u from both sides:
(14 u - 6 u) - 30 = (6 u - 6 u) - 24
14 u - 6 u = 8 u:
8 u - 30 = (6 u - 6 u) - 24
6 u - 6 u = 0:
8 u - 30 = -24
Add 30 to both sides:
8 u + (30 - 30) = 30 - 24
30 - 30 = 0:
8 u = 30 - 24
30 - 24 = 6:
8 u = 6
Divide both sides of 8 u = 6 by 8:
(8 u)/8 = 6/8
8/8 = 1:
u = 6/8
The gcd of 6 and 8 is 2, so 6/8 = (2×3)/(2×4) = 2/2×3/4 = 3/4:
Answer: u = 3/4

Answer:
-5/8h + 7
Step-by-step explanation:
First you need to combine like terms (1/8h and -3/4h)
So 1/8h - 3/4h is -5/8h
Then we have our 7 left over
So the answer is -5/8h + 7
Answer:
C. 2, 8, 10.
Step-by-step explanation:
For A, n = 13:
26 > 13 + 15
26 > 28 is false. Therefore A is false.
For B, n = 15:
26 > 15 + 15
26 > 30 is false. Therefore B is false.
For D, n = 11:
26 > 11 + 15
26 > 26 is false. Therefore D is false.
Therefore, C is the correct answer.
