Answer:
hence small rolls 60 and large rolls 70
Step-by-step explanation:
let club sold s small rolls
hence club sold s+10 large rolls
earning from small roll 3s
earning from large rolls 4.5(s+10)
hence
4.5(s+10) - 3s = 135
or 4.5(s+10) = 3s +135
3s +135 = 4.5(s+10)
3s +135 = 4.5s +45
4.5s +45 = 3s +135
4.5s -3s = 135-45
1.5s = 90
s = 90/1.5
s= 60
s+10 = 70
hence small rolls 60 and large rolls 70

Answer:
-x + 9

2x+3+8-3x-2 = 2x - 3x + 3 + 8 -2 = -x +9
Here is the answer I hope that it helped
Let's make the variable P and M.
4M=P
P+6+6+M=57
Let's put the first equation in as Paula's age.
4M+12+M=57
5M+12=57
5M=45
45÷5
9
Mary's present age is 9, so Paula's age is 36.
Let's check the sum of their ages in 6 years.
15+42
57
