Step-by-step explanation:
y=-4x+5
y=x+10
------------
-4x+5=x+10
-4x-x+5=10
-5x=10-5

x=5/-5
x=-1
The smallest and largest data values are 1 unit away from each other
For part a you take the number of orange jelly beans which is 130 and green jelly beans which is and insert the colon 130:10. If you need to simplify it then you would put it over as a fraction 130/10 simplified is 13:1
For part b you would do something similar there are an unknown amount of yellow jelly beans to 636 jelly beans. So you would add all the jelly beans you know the amounts of then subtract it from the total. 138+130+10 less from 636 is 358. So you have 358 yellow jelly beans. To conclude the ratio would be 358:636, simplified it would be 179:318
