Answer:
315 people
Step-by-step explanation:
Using the given ratio, we can figure out the number of children on the train by doing cross multiplication.
Let x = # of children on train.
7/2 = 245/x
7x = 490
x = 70 children
The total number of people = 70 + 245 = 315 people total

Answer:
C
Step-by-step explanation:
Since GJ bisects ∠ FGH , then ∠ FGJ = ∠ JGH = x + 14
∠ FGH = ∠ FGJ + ∠ JGH , substitute values
4x + 16 = x + 14 + x + 14 = 2x + 28 ( subtract 2x from both sides )
2x + 16 = 28 ( subtract 16 from both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Thus
∠ FGJ = x + 14 = 6 + 14 = 20° → C
Answer:
D - All rational numbers are integers.
