Lisa has 5 more green marbles than blue marbles. She has a total of 40 green and blue marbles. Which system of equations represents this situation if x is the number of green marbles and y is the number of blue marbles?
x=y+5
x+y=40
y = x + 5
x + y = 40
i think its goood
Use the substitution method and she has 7 green marbles and 28 blue marbles
5+X=Y
X+Y= 40
Well, Lisa's green marble obsession seems to be in full swing! Let's figure out the system of equations to represent this situation.
First, we know that Lisa has 5 more green marbles than blue marbles. So, x (the number of green marbles) would be equal to y (the number of blue marbles) plus 5. In equation form, this would be: x = y + 5.
Secondly, we know that Lisa has a total of 40 green and blue marbles. Therefore, x (the number of green marbles) plus y (the number of blue marbles) would equal 40. In equation form, this would be: x + y = 40.
Put it all together, and we get the system of equations:
x = y + 5
x + y = 40
Green marbles, blue marbles, and equations, oh my! Hope that helps!
To represent this situation with a system of equations, we need to set up equations based on the given information.
Let's start by stating the facts we know:
1) Lisa has 5 more green marbles than blue marbles.
2) She has a total of 40 green and blue marbles.
Let x represent the number of green marbles and y represent the number of blue marbles.
Based on the first fact, we can write an equation:
x = y + 5
This equation represents the fact that Lisa has 5 more green marbles than blue marbles.
Based on the second fact, we can add the number of green and blue marbles together to get the total number of marbles:
x + y = 40
This equation represents the fact that the total number of green and blue marbles is 40.
Therefore, the system of equations that represents this situation is:
x = y + 5
x + y = 40
