Step-by-step explanation:
Let the number of red marbles be r
Let the number of black marbles be b
<u>Given the following data;</u>
Total number of marbles = 120
Translating the word problem into an algebraic equation, we have;
.......equation 1
........equation 2
Substituting the value of "r" into equation 2, we have;



b = 6 marbles.
To find the number of red marbles;
From equation 1;
Substituting the value of "b" into equation 1, we have;

<em>r = 114 marbles.</em>

Answer:
6
simplified to 6
Step-by-step explanation:
Hey, Ace here!
So we have to round 6
to the nearest half
So we look at the denominator.
What is half of 8?
4 of course.
So that means that one of the answers could be 6
But since a half + a half = a whole (1), a half could also be a whole number.
So that means the answer could either be 6
or 7
Which one is 6
closer to?
It's closer to 6
