You do add the two negatives and get a negative answer but -3 + -5 = -8
Answer:
d = 48t will represent the distance 'd' traveled in 't' hours.
Step-by-step explanation:
Jason leaves Detroit at 2:00 PM and passes through Ann Arbor at 2:50 PM which is 40 mi distant from Detroit.
Speed during this journey was constant.
Jason traveled 40 mi in 50 minutes or
hours from Detroit to Ann Arbor.
By the formula,
Speed = 
Speed = 
= 48 mi per hour
If he travels 'd' miles in 't' hours then by the formula of speed,
48 = 
d = 48t
The answer would be w= 7z/2 Isolate the variable but dividing each side by factors that don’t contain the variable
Answer:
B: Survey 3 randomly selected students from every homeroom.
Step-by-step explanation:
This would be the best way to survey, because all the others have some sort of variable. The principle doesn't know who buys lunch and who doesn't, so why would he just ask kids who ride in a car as there are kids who ride buses, or only 7th grade students, so the best answer would be something that everyone has, like homeroom.
Answer:
x = 5 and x = 
Step-by-step explanation:
To find the zeros equate f(x) to zero, that is
(2x - 1)(x - 5) = 0
equate each factor to zero and solve for x
2x - 1 = 0 ⇒ x = 
x - 5 = 0 ⇒ x = 5
