Answer:
Step-by-step explanation:
If we call the points she scored in the last game x, we can actually write out an equation to describe what is being said. 20=11+(3/5)x. Hopefully that makes sense. 3/5 of the previous score plus 11 is 20. Anyway, you can just solve this algebraic expression for x.
20=11+(3/5)x subtract 11 from both sides
9 = 3/5 x Multiply both sides by 5
45 = 3x then divide both sides by 3
15 = x And there you go.
Note, since both factors have the same denominator, we can add the numerators together.
Numerator :
5n + (2m + 4n) = 5n + 2m + 4n = 9n + 2m
Denominator :
30m
Thus,
= (9n + 2m) / 30m
