Answer:
7+(3(-4)2
Step-by-step explanation:
Let us calculate each one of them
1. -5(7+(-14))-30
= -5(7-14)-30
= -5(-7)-30
=35-30
=5
2. (15-7)-(9÷3)
= (8)-(3)
=5
3. -2[12÷(-3)]
= -2[-4]
= 8
4. 7+3(-4)(2)
= 7+(-24)
= -17
Hence only forth option is negative value

Answer:
5.2%.
Step-by-step explanation:
After 1 hour (60 / 100) * 700 = 420 gallons of beer have been exchanged.
So we have 420 gallons of 6% and 280 gallons of 4% after 1 hour.
So the strength at that time = (420* 6) + 280*4) / 700
= 5.2%.
