13.slope =-9 intercept 0
Answer:
square root of 25=5 and square root of (x+9)=(x+9) so the answer is.... x+9=+-5
Step-by-step explanation:
5 * 12 = 60 (for the whole area)
3 * 2 = 6 (for the missing space)
6 + 2 = 8
12 - 8 = 4
4 * 3 = 12
12 / 2 = 6
6 + 6 = 12
60 - 12 = 48
Answer: 48
Sorry if this isn’t right :(
Answer:
10 hours.
Step-by-step explanation:
Two bicyclists are 200 miles apart when they start racing towards one another.
Their speeds are 12 mph and 6 mph respectively.
Distance = speed × time
Let the time taken by bicyclists = t
We have to calculate the time when they 20 miles apart this means they have covered the distance of 200 - 20 = 180 miles
t(12mph) + t(6mph) = 180
18t = 180
t = 
t = 10 hours
It will take 10 hours to both the bicyclists before they are 20 miles apart.
