Answer:
9/20
Step-by-step explanation:
You set the fraction up at first as 45/100. Then you know that 5 goes into each so you divide by 5 
45/5=9
100/5=20
You get 9/20, and this is in simplest form.
Answer: 63
Step-by-step explanation: 21+21+21
Answer:612
Step-by-step explanation: take 656 and subtract 44 diamonds to get the remaining rubies 656-44= 612
Any multiple of (-2x+3y=18) would constitute an "other equation" forming a system with an infiinite number of solutions. The reason for that is that the two equations would be "dependent."
On the other hand, looking at the system
<span>-2x+ 3y= 18
</span><span>-2x+ 3y= 19
we see that there is no solution. Why? Because -2x + 3y cannot equal 18 and 19 at the same time. You'd have two non-intersecting, parallel lines.

Answer:
the answer should be 14 because he hits a ball everyother game so every other game for 28 is 14
