Ateacher writes on the board: "elijah has 3 times as many coins as tom, and mark has twice as mainly coins as elijah. then she asks, mark has how many times as many as tom

Mark has 6 times as many as Tom

Step-by-step explanation:

Elijah = E

Tom = T

Mark = M

Translate the information into mathematical equation :

E = 3T

M = 2E

How many times Mark has as many as Tom ?

M = T ?

M = 2 E    (Remember, E = 3T, insert this)

M = 2 ( 3 T )

M = 6 T

Mark has 6 times as many as Tom

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
