Answer: 9.2 miles
Step-by-step explanation:
B. Is the correct answer. For part B, he can buy 15 balloons since X=15. Plug this back into the equation to check: 2(15)+20=50.
2(15)=30+20=50.
80,000 per year....there are 12 months in a year
80,000 / 12 = 6666.67 per month
There are 16 possible outcomes.
This is found by taking the number of possible outcomes for each toss, 2, and raising it to the 4th power (for 4 tosses):
2⁴ = 2*2*2*2 = 16
