567/71 because passengers/(train cars/passengers) = train cars
71 x 7 = 497 (not enough)
71 x 8 = 568 (enough)
Answer: 8 train cars
Answer:
They both have H hoel
Step-by-step explanation:
\
Y+8 = -3(x-7)
Distribute the -3
y +8 = -3x +21
Subtract 8 from both sides
Y = -3x +21 -8
Y= -3x+13
Answer:
8
Step-by-step explanation:
Let q = quarters
Let d = dimes
q + d = 13
0.25q + 0.10d = 2.75
You have two equations and two unknowns.
Take it from here.
