The correct answer is Choice E: 1 milligram.

The prefix milli means "1/1000". That means a milligram is 1/1000th the size of a gram. All of the other weights in the list are larger.

A vegetable store sold 3 tons of vegetables less on the first day than on the second, and on the third day it sold 5/9 of the am
Ilya [14]
Let
x---------> <span>quantity (ton) of vegetables sold the first day
</span>y---------> quantity (ton)  of vegetables sold the second day
z---------> quantity (ton) of vegetables sold the third day

we know that
x=y-3---------> equation 1
z=(5/9)*(x+y)------> equation 2
x+y+z=98-----> equation 3
substitute equation 2 in equation 3
x+y+[(5/9)*(x+y)]=98----> multiply by 9----> 9x+9y+5x+5y=882
14x+14y=882-----> equation 4

to resolve the equations system formed by
x=y-3
14x+14y=882

using a graph tool
see the attached figure
the solution is
x=30
y=33
x+y+z=98----> z=98-(x+y)----> z=98-63---> 35

the answer is
vegetables sold the first day----> 30 ton
vegetables sold the second day----> 33 ton
vegetables sold the third day------> 35 ton
