Hello there!
Based from this question above, what this is asking is to find how much does 17% goes into 400 marbles.
We want to know how many marbles are in this 400 marbles. (This would be the key point)
We do (17% x 400).
By putting the "%" symbol this allows us the understand that we are trying to find out how many blue marbles they're going to be.
By multiplying them both together, we got our answer as (68) marbles.
Your correct answer would he 68.
I hope this helps you!
None of the above are equivalent to -6(b+2)+8
Y=2x-1
y=-3x+14
First you would substitue one of the y's for the other so
2x-1=-3x+14
no you would solve for x...
add one on both sides
2x=-3x+15
now add 3x to both sides which becomes
5x=15
divide 5 on both sides which gives you x=3
now to solve for y plug into any one of the equations(doesn't matter which one) from before 3 for x and solve
y=2(3)-1
y=6-1
y=5
And that is you answer y=5
145-13-9-5 that what your looking for
It is adding one little percentage of increase here. or, 1.1 each time....hope that this helps.
