Answer:
x=-2, y=1
Step-by-step explanation:
To solve a system of equations, you set x+3 and 2x+5 equal to each other and solve. This simplifies to x=-2. Then you plug itin to one of the equations to get y. Hope this helps and have a magnificent day!!!!! Stay safe!!!
If William has 195 marbles, let's find 4/5 of that.
195 * 4/5 = 156
156 is 2/5 of the marbles Daniel has.
Now we must multiply by the reciprocal
156 * 5/2 ( to find all of Daniel's marbles, not just 2/5) = 390 marbles
Daniel has 390 marbles.
4.781, 4.782,4.783,4.784,4.785
I can't explain though:(

What you have here is the fibonacci sequence.
Each number in the sequence adds itself to the number before it.
1+1 = 2
1+2 = 3
3+2 = 5
5+3 = 8
8+5 = 13
the sequence is 0,1,1,2,3,5,8,13
