Answer:
Step-by-step explanation:
6(6x+6)-5 = 1+6x
36x+36-5 =1+6x
36x+31 = 1+6x
-6x -6x
30x+31 = 1
-31 -31
30x = -30
________ (divide)
30
x=-1
(40 mile / hr) x (5280 feet / 1 mile) x (1 hr / 3600 s) = 58.67 ft / s
The Jackrabbits' speed may also be expressed as 58.67 ft / s.
In order to determine the correct answer, it would be helpful to set up equations. We do as follows:
Let x = students
y = adults
x + y = 215
.50x + 2y = 250
SOlving simultaneously, we have:
x = 120 students
y = 95 adults
Hope this answers the question. Have a nice day.
