No they’re not equivalent because for 3(2n+9) when you distribute the 3 you get 6n+27 & 5n+9+n equal to 6n+9 when you combine like terms (add the n’s).
Answer:
- sugar cookies -- $4
- oatmeal cookies -- $8
Step-by-step explanation:
Using "s" and "o" to represent the prices of packs of sugar and oatmeal cookies, respectively, we can write the revenue equations as ...
10s +2o = 56
9s +3o = 60
In standard form (with common factors removed), these equations are ...
5s + o = 28
3s + o = 20
Subtracting the second equation from the first, we find ...
(5s +o) -(3s +o) = (28) -(20)
2s = 8 . . . . simplify
s = 4
Substituting into the first equation, we have ...
5·4 +o = 28
o = 8 . . . . . . subtract 20
The price of a pack of sugar cookies is $4; of oatmeal cookies, $8.
