Answer:
So there are 8 red and 5 brown M&M
Step-by-step explanation:
Let X is red M&M
Let Y is brown M&M
We know that:
- 3 more red M&Ms than brown <=> X = Y +3
- A bowl contains 13 red and brown M&Ms <=> X + Y = 13
substitute X into the second equation: (Y + 3) + Y = 13
<=> 2Y = 10
<=> Y =5
=> X = 5 + 3 = 8
So there are 8 red and 5 brown M&M
Answer:
There are five(5) brown M&Ms and Eight(8) red M&Ms.
Step-by-step explanation:
If the number of brown M&Ms =b
If there are 3 more red M&Ms than brown, then the number of red M&Ms, r=b+3
The total of Red and Brown M&Ms =13
r+b=13
Since r=b-3
b+3+b=13
2b=13-3
2b=10
Divide both sides by 2
b=5
Number of red M&Ms
r=b+3=5+3=8
Therefore, there are 5 brown M&Ms and 8 red M&Ms.
