4/5n – 1/5 = 2/5n
Add 1/5 to both sides
4/5n = 2/5n + 1/5
Subtract 2/5n from both sides
2/5n = 1/5
Divide both sides by 2/5
n = 1/2
Answer:
Step-by-step explanation:
= n^2 + (3n^2 + 3n + 1 / n-3) = 3n
= BTW (/ = Fraction) and ^ means exponent
= n^2 + 3n + (12n + 1 / n - 3) = 12
= 37 / n - 3
Answer: n^2 + 3n + 12 +( 37 / n - 3)
Hope this helps :D
Divide 5/8 in 1 5/8 first. and get 0.625 now take the one and get 1.625.
now take the 8 1/4 and do the same to get 8.25
now divide 8.25 by 1.625.
and get 5.07692308
so the answer is 5

If she has 68 lollipops, and she had 8 remaining, we should subtract the two.
68 - 8 = 60
So now we know she gave away 60 lollipops in total.
We know she gave 3 to each of her friends, so we would divide 60 by 3.
60/3 = 20
So she has 20 friends.
