Answer:
D
Step-by-step explanation:
The problem with D is that 7 + 11 = 18. The rule is any two sides must exceed the third. D gives the shorter + the middle length = the longest length.
That can't work. All the others are fine.
Answer: Where's the graph
Step-by-step explanation: Put up a graph
Answer:
15 bikes, 6 gocarts
Step-by-step explanation:
so both the vehicles have 1 seat each
the bicycles will be represented by B
the gocarts will be represented by G
because there are only 1 seat per for a total of 21 seats, we have this as the first equation:
B + G = 21
Gocarts have wheels and bikes have 2 seats, so we have this equation:
2B + 4G = 54
from there we can simply replace b with g to find the amount of gocarts first:
B + G = 21
B = 21 - G
2(21-G) + 4G = 54
42 - 2G + 4G = 54
2G + 42 = 54
2G = 12
G = 6
So there are 6 gocarts.
plug in 6 for g
B + 6 = 21
B = 15
therefore, there are 15 bikes and 6 gocarts
