The ratio of adults to children on a train in 7:2. There are 245 adults on the train. Find the total number of people on the tra
in?
1 answer:
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

Oh idk and idc cuz i just really don’t so yea
B. One is the answer because the longest line that would match is through c and b.
Vertical angles are equal
5x - 40 = 3x + 8
5x - 3x = 8 + 40
2x = 48
x = 48/2
x = 24
m∠ABC = 3x + 8 = 3 * 24 + 8 = 80°
(or m∠ABC = 5x - 40 = 5 * 24 - 40 = 80°)
V=lwh
V= (4)(4)(4)
V= 64 in cubed
(x² + 10)(6x - 5)
6x³ - 5x² + 60x - 50 or the second option
