Answer: they will meet after 3 hours.
Step-by-step explanation:
Let t represent the number of hours it will take them to meet.
A walker and a cyclist are 45 miles apart. If they move towards each other, in t hours, they would have covered a total of 45 miles
Distance = speed × time
They move towards each other with speeds of 5 mph and 10 mph respectively. It means that the distance covered by the walker in t hours is 5 × t = 5t
Also, the distance covered by the cyclist in t hours is 10 × t = 10t
Since the total distance covered us 45 miles, then
5t + 10t = 45
15t = 45
t = 45/15
t = 3 hours
Answer:

Answer:
Step-by-step explanation:
So basically the equation is (x+2) times (x+6). Use the FOIL method to multiply across like this:
x*x + x*6 + 2*x + 2*6
Combine like terms
x^2 + 8x + 12

Answer:
An equation for this would be : 36=3+x+3+X+5+5
the simplified version would be: 20=2x
The value of x = 10 feet
Step-by-step explanation:
Since perimeter is all the sides added together, and 36 ft is the perimeter,
think of a rectangle, 2 sides would be 3+x and the other 2 would be 5.
thus,
36=3+x+3+x+5+5
now add all like terms and you get 36=16+2x
subtracting 16 on both sides,
20=2x
dividing by 2 both sides,
x=10 feet.
