Answer:
You would get tails 75 times, or 75:200
Step-by-step explanation:
5:8 = x:200
multiply 8 by 25 to get 200
multiply 5 by 25 to get x (125)
Probability to get heads is 125 so subtract 200 by 125
200 - 125 = 75
Answer:
5
Step-by-step explanation:
Deena drove:
585 miles/9 hrs
....which means
her average rate was:
65miles/hour
whereas
Kristen drove:
605 miles/11 hrs
....meaning
her average rate was:
55 miles/hour
Therefore, Deena drove at a faster rate than Kristen
6x+1 / 2x +6 - 5/2
Factor 2 out of the denominator of the first fraction:
6x+1 / 2(x+3) - 5/2
Rewrite 5/2 to have a common denominator with the first fraction:
6x+1/2(x+3) - 5(x+3) / 2(x+3)
Simplify terms:
6x +1 - 5(x+3) / 2(x+3)
Use distributive property:
6x +1 - 5x -15 / 2(x+3)
Combine like terms for final answer:
(x-14) / 2(x+3)
