5/11, 2/3, 7/8. 5/11 is a little less than half, so that can be ruled out. 2/3 is equivalent to 4/6 which is less than 7/8.<span />
Answer:
x = -30/7

Answer: The correct answer would be a=1.
Answer: D. -4F
Step-by-step explanation:
Let's use simple math. 1 - 5 = -4 or -8 divided by 2 = -4, right?
Same idea, so now lets apply it.
If it decreases -8F in only two hours you just simply divide the temperature by the hour.
Looking at problem A that just would not make sense, how could it decrease while staying at the same number?
Problem B also wouldn't make sense because a negitive plus negitive equals a negitive, same with subtracting. So 10 is inncorrect
Problem C also is inncorrect because 8 divided by 2 = 4, not 6
So, D is correct because -8 divided by 2 equals = -4
Hope this helps!
