Answer:
The cousins have 4 bags of white marbles and 4 bags of pink marbles.
Step-by-step explanation:
If x is the number of bags with white marbles and y is the number of bags with pink marbles, we can write the following system:
x + y = 8 -- Equation 1
5x + 7y = 48 -- Equation 2
5x + 5y = 40 -- Equation 3 (Multiply Equation 1 by 5)
2y = 8 -- (Subtract Equation 3 from 2)
y = 4 -- (Divide both sides by 2)
x + 4 = 8 -- (Substitute y = 4 into Equation 1)
x = 4 -- (Subtract 4 from both sides)
Answer:
2 = (2/3)*(6)+b
2 = 4+b
b= -2
so slope intercept form is y = (2/3)x -2
To find the point slope form, simply plug in m and the point given.
y-2 = (2/3)*(x-6)
Step-by-step explanation:
"In our class we have 3 books. My teacher says that we need to increase that number of books by 1/8 with each student. If they are 7 students how many books will the class have now?"
Ok there's a quick example but here is how to solve it.
You need to make the 3-fraction friendly and put a one under it
1/3 and now you can multiply 3/1 x 7/8.
Which will now give you 21/8 and simplified it will be 2 5/8
So final answer would be 21/8 = 2 5/8.
