Answer:
x = 6
Step-by-step explanation:
7 x = 56-14

Answer:
a) ok, heres what u graph, and ur ordered pairs
graph the following points:
(0,0) (1,5) (2,10) (3,15) (4,20) (5,25) (6,30) (7,35), and so on
b) One of the ordered pairs I can use is (1,5). This is beacuse the ordered pair explains that for every video game (x), 5 will be the cost (y).
Answer:
Speed of river's current = 5 mph
Step-by-step explanation:
Let 'd' be the distance covered
Let x be the speed of the rivers current
Speed upstream = 15-x
speed downstream = 15+x
Time = distance / speed
time upstream = 
time downstream = 
the ferry trip upstream takes twice as long as its return trip downstream
= 
divide both sides by d
= 
cross multiply


Add 2x on both sideds

subtract 15 from both sides and divide by 3

x=5
Speed of river's current = 5 mph
