Answer D on edg.
Given that Antonia and Carla have the same percentage of marbles and Antonia has 4 green marbles out of 16 marbles , to calculate the number of marbles that Carla has that aren't green we proceed as follows;
let the total number of Carla's marbles be x;
the percentage of green marbles that Antonia has is:
4/16×100=25%
since they have the same percentage then:
number of green marbles Carla has is 10:
this is 25% of x, hence:
10/x×100=25
1000/x=25
1000=25x
thus
x=1000/25
x=40
Carla has a total of 40 marbles. Thus the number of marbles which are not green will be:
40-10=30 marbles
Answer:
4m + 6
Step-by-step explanation:
Hello There!
We can simplify the expression by distributing the 2 to what is inside of the parenthesis ( 3 and 2m)
3 * 2 = 6
2 * 2m = 4m
so the expression 2(3 + 2m) simplified would be
4m + 6
