Answer:
15
Step-by-step explanation:
there are 2 red marbles for every 5 blue marbles, and we know that there are 6 red marbles total.
2x3=6, so we know that there are 3 sets of 2 red marbles, meaning there is also 3 sets of 5 blue marbles.
So there are 3x5=15 blue marbles in the bag
Answer:
128
Step-by-step explanation:
160 x .20 = 32
160 - 32 = 128
To be able to find the value of X, we have to cross multiply the two fractions then solve the equation.
As so,
6/4 = 15/x
Cross Multiply:
6 x X = 6x
4 x 15 = 60
We cross multiplied, now we can set up the equation:
6x = 60
Simplify: (Get X by itself)
Divide 6 on each side
6 / 6x = 60 / 6
x = 60 / 6
x = 10
Now we have the total of X! To check our answer, we can substitute X for 10 in the original equation.
As so:
6/4 = 15/10
6/4 = 1.5
15/10 = 1.5
Correct! Our answer is X = 10!

1, because the two lines on the side hit eachother,
so those arent paralell but the top and bottom are paralell because they dont touch
