The rule is minus 5.
So 20, 15, 10, 5, 0, -5
For an equal number of servings, the bananas will have three times as much sugar.
To put it in perspective:
When we have one serving of each fruit, the carrot will give you 5 grams of sugar whereas banana will give you 15 grams.
Hope this helps!
If you took

of a pie then only ate

of that slice, you ate

of

.

Simplify.

So, you ate 1/6 of the pie.
An equation is:
2(x+3)-7=9
Distribute the 2
2(x)+2(3) -7=9
2x+6-7=9
Combine like terms
2x-1=9
Add one to both sides
2x-1+1=9+1
2x=10
Divide both sides by two to isolate the variable.
2x/2=10/2
x=m

keep in mind that, a negative coefficient to "x", will make the graph reflect over the y-axis.
