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
Y - y₁ = m(x - x₁)
y - 2 = -3(x - (-5))
y - 2 = -3(x + 5)
y - 2 = -3(x) - 3(5)
y - 2 = -3x - 15
<u> + 2 + 2</u>
y = -3x - 13
2x+1=5x-20
you want to find the x value so you want to isolate x to do this you have to subtract 2x on both sides. After you have accomplished this you add 20 on both sides once again and then you divide what your answer from what you added by three.
2x+1=5x-20
-2x -2x
________
1=3x-20
+20 +20
_______
21/3=3x/3
7=x
