Answer:
n = - 1
Step-by-step explanation:
Given
- 8n + 4(1 + 5n) = - 6n - 14 ← distribute and simplify left side
- 8n + 4 + 20n = - 6n - 14
12n + 4 = - 6n - 14 ( add 6n to both sides )
18n + 4 = - 14 ( subtract 4 from both sides )
18n = - 18 ( divide both sides by 18 )
n = - 1
Answer:
work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease.

Answer: Part A = 12 candles per hour
Step-by-step explanation:
48/4 = 12
2x²-3x-15=5
2x²-3x-15-5=0
2x²-3x-20=0
½(2x+5)(2x-8)
-2x=-5
x=-5/2
2x-8=0
2x=8
x=4
